Semen juga merupakan jenis bahan bangunan material rumah yang paling sering digunakan, bahan bangunan material ini juga digunakan untuk dapat membuat sebuah pondasi. Selain kayu, logam dan besi, semen juga merupakan elemen yang sebenarnya tidak bisa ditinggal.
Saat ini, banyak sekali jenis semen yang beredar di pasaran toko bahan bangunan material. Namun, banyak sekali dari orang–orang yang tidak tahu cara memilih semen yang baik. Semen yang baik adalah semen yang bisa menghasilkan bangunan rumah minimalis yang berkualitas dan juga bagus. Yang paling penting saat pembelian semen itu adalah dengan mencoba kelunakan dan kelembutan semen dengan menekannya meski masih berada dalam kemasannya. Jika semen yang di tekan dari luar kemasan terasa keras, itu tandanya semen sudah terlalu lama disimpan dan sudah tidak dalam kondisi yang bagus lagi.
Lalu semen yang baik juga akan terlihat ketika sudah dikeluarkan dari kemasannya. Semen yang baik kualitasnya, adalah semen yang seluruh butirannya bisa terurai dan nampak lembut seperti debu, juga tidak menggumpal. Tapi jika semen tersebut mulai menggumpal dan terlihat kasar, maka kualitasnya juga sudah pasti berkurang. Apalagi jika sudah terlihat mengeras dan membatu seperti kerikil.
Kemudian setelah tahu dan mendapatkan semen yang baik, tentu kita juga harus tahu cara untuk menyimpan semen yang baik agar tidak turun kualitas semennya. Karena jika terjadi salah–salah dalam menyimpan semen, bisa akan membuat semen menjadi rusak dan juga mengeras. Kita tentu tidak ingin hal itu akan terjadi bukan? Oleh karena itu, ada sedikit cara untuk dapat menyiasati agar hal tersebut tidak terjadi.
Material bahan bangunan semen yang sudah dibuka atau yang belum dibuka harus disimpan dalam ruangan yang tertutup atau minimal terlindung dari sinar matahari dan hujan. Selain itu, kita juga harus memperhatikan permukaan lantainya. Sebaiknya, kita harus menyimpannya di permukaan lantai yang datar dan tidak berupa tanah.
Dan untuk semen yang belum dibuka dari kemasannya, kita juga bisa menggunakan kayu sebagai wadah landasan. Jadi, semen tidak langsung diletakkan pada lantai. Dan metode ini tentu telah memiliki tujuan. Jika terjadi penguapan air dan pengembunan didalam tanah atau dibawah lantai maka tidak akan langsung terkena semen. Otomatis, semen akan terhindar dari kerusakan. Jika semen yang disimpan dalam jumlah yang banyak, maka bisa disimpan dengan menggunakan konsep susunan batu bata. Saling berjajar, namun pada bagian atasnya telah diletakkan dalam posisi yang saling menyilang. Hal ini untuk dapat menghindari susunan kemasan semen agar tidak bisa jatuh dan tumpah. Selain itu, tujuan untuk menyimpan semen dengan metode ini adalah agar semen bisa mendapatkan celah atau ruang untuk mendapatkan udara dan terhindar dari penggumpalan.
Dan dari keadaan yang disimpan, untuk dapat menggunakan semen haruslah diambil dari stok pertama atau dari tumpukan pertama (bawah). Hal ini telah dilakukan agar menghindari penggumpalan pada semen karena disimpan terlalu lama. Dalam penyimpanan semen, hal yang harus diperhatikan juga adalah kebersihan dari tempat penyimpanan. Tempat yang lembap bisa akan membuat semen cepat menggumpal dan mengeras jauh lebih cepat. Begitu pula dengan dengan sirkulasi udara yang pengap, hal itu bisa menimbulkan masalah yang sama. Namun, jika tidak terdapat tempat penyimpanan di dalam ruangan atau seperti gudang untuk dapat menyimpan semen, maka sebaiknya gunakan tempat yang teduh dan lindungi dari sinar matahari. Untuk perlindungan lebih maksimal, kita bisa gunakan kain terpal.
Semoga tips dalam memilih bahan bangunan khususnya semen bisa bermanfaat untuk Anda! Selamat berbelanja!
TIPS MEMILIH BAHAN BANGUNAN
Even as a high school student, Dave Goldberg was urging female classmates to speak up. As a young dot-com executive, he had one girlfriend after another, but fell hard for a driven friend named Sheryl Sandberg, pining after her for years. After they wed, Mr. Goldberg pushed her to negotiate hard for high compensation and arranged his schedule so that he could be home with their children when she was traveling for work.
Mr. Goldberg, who died unexpectedly on Friday, was a genial, 47-year-old Silicon Valley entrepreneur who built his latest company, SurveyMonkey, from a modest enterprise to one recently valued by investors at $2 billion. But he was also perhaps the signature male feminist of his era: the first major chief executive in memory to spur his wife to become as successful in business as he was, and an essential figure in “Lean In,” Ms. Sandberg’s blockbuster guide to female achievement.
Over the weekend, even strangers were shocked at his death, both because of his relatively young age and because they knew of him as the living, breathing, car-pooling center of a new philosophy of two-career marriage.
“They were very much the role models for what this next generation wants to grapple with,” said Debora L. Spar, the president of Barnard College. In a 2011 commencement speech there, Ms. Sandberg told the graduates that whom they married would be their most important career decision.
In the play “The Heidi Chronicles,” revived on Broadway this spring, a male character who is the founder of a media company says that “I don’t want to come home to an A-plus,” explaining that his ambitions require him to marry an unthreatening helpmeet. Mr. Goldberg grew up to hold the opposite view, starting with his upbringing in progressive Minneapolis circles where “there was woman power in every aspect of our lives,” Jeffrey Dachis, a childhood friend, said in an interview.
The Goldberg parents read “The Feminine Mystique” together — in fact, Mr. Goldberg’s father introduced it to his wife, according to Ms. Sandberg’s book. In 1976, Paula Goldberg helped found a nonprofit to aid children with disabilities. Her husband, Mel, a law professor who taught at night, made the family breakfast at home.
Later, when Dave Goldberg was in high school and his prom date, Jill Chessen, stayed silent in a politics class, he chastised her afterward. He said, “You need to speak up,” Ms. Chessen recalled in an interview. “They need to hear your voice.”
Years later, when Karin Gilford, an early employee at Launch Media, Mr. Goldberg’s digital music company, became a mother, he knew exactly what to do. He kept giving her challenging assignments, she recalled, but also let her work from home one day a week. After Yahoo acquired Launch, Mr. Goldberg became known for distributing roses to all the women in the office on Valentine’s Day.
Ms. Sandberg, who often describes herself as bossy-in-a-good-way, enchanted him when they became friendly in the mid-1990s. He “was smitten with her,” Ms. Chessen remembered. Ms. Sandberg was dating someone else, but Mr. Goldberg still hung around, even helping her and her then-boyfriend move, recalled Bob Roback, a friend and co-founder of Launch. When they finally married in 2004, friends remember thinking how similar the two were, and that the qualities that might have made Ms. Sandberg intimidating to some men drew Mr. Goldberg to her even more.
Over the next decade, Mr. Goldberg and Ms. Sandberg pioneered new ways of capturing information online, had a son and then a daughter, became immensely wealthy, and hashed out their who-does-what-in-this-marriage issues. Mr. Goldberg’s commute from the Bay Area to Los Angeles became a strain, so he relocated, later joking that he “lost the coin flip” of where they would live. He paid the bills, she planned the birthday parties, and both often left their offices at 5:30 so they could eat dinner with their children before resuming work afterward.
Friends in Silicon Valley say they were careful to conduct their careers separately, politely refusing when outsiders would ask one about the other’s work: Ms. Sandberg’s role building Facebook into an information and advertising powerhouse, and Mr. Goldberg at SurveyMonkey, which made polling faster and cheaper. But privately, their work was intertwined. He often began statements to his team with the phrase “Well, Sheryl said” sharing her business advice. He counseled her, too, starting with her salary negotiations with Mark Zuckerberg.
“I wanted Mark to really feel he stretched to get Sheryl, because she was worth it,” Mr. Goldberg explained in a 2013 “60 Minutes” interview, his Minnesota accent and his smile intact as he offered a rare peek of the intersection of marriage and money at the top of corporate life.
While his wife grew increasingly outspoken about women’s advancement, Mr. Goldberg quietly advised the men in the office on family and partnership matters, an associate said. Six out of 16 members of SurveyMonkey’s management team are female, an almost unheard-of ratio among Silicon Valley “unicorns,” or companies valued at over $1 billion.
When Mellody Hobson, a friend and finance executive, wrote a chapter of “Lean In” about women of color for the college edition of the book, Mr. Goldberg gave her feedback on the draft, a clue to his deep involvement. He joked with Ms. Hobson that she was too long-winded, like Ms. Sandberg, but aside from that, he said he loved the chapter, she said in an interview.
By then, Mr. Goldberg was a figure of fascination who inspired a “where can I get one of those?” reaction among many of the women who had read the best seller “Lean In.” Some lamented that Ms. Sandberg’s advice hinged too much on marrying a Dave Goldberg, who was humble enough to plan around his wife, attentive enough to worry about which shoes his young daughter would wear, and rich enough to help pay for the help that made the family’s balancing act manageable.
Now that he is gone, and Ms. Sandberg goes from being half of a celebrated partnership to perhaps the business world’s most prominent single mother, the pages of “Lean In” carry a new sting of loss.
“We are never at 50-50 at any given moment — perfect equality is hard to define or sustain — but we allow the pendulum to swing back and forth between us,” she wrote in 2013, adding that they were looking forward to raising teenagers together.
“Fortunately, I have Dave to figure it out with me,” she wrote.
