“…Beton ringan foam sendiri merupakan campuran semen, air, agregat halus dan bahan tambah (admixture) tertentu dengan sifat beton ini terdapat gelembung-gelembung dalam bentuk busa dalam adukan semen sehingga terjadi banyak pori-pori udara di dalam bentonnya [4], [5]. Pada dasarnya beton ringan sendiri memiliki berat jenis yang lebih ringan, mempunyai sifat meredam suara yang baik, bersifat isolator terhadap panas dan karena bobotnya yang ringan memudahkan dalam hal pengiriman dan pemasangan serta cocok untuk perancangan rumah tahan gempa [6]- [8]. Menurut SNI, berat jenis maksimum beton ringan struktur yaitu 1840 kg/m 3 dengan kuat tekan minimum 28 Mpa [9].…”

Teknologi terbarukan mengenai penggunaan beton ringan telah banyak dikembangkan. Akan tetapi dalam penggunaan beton ringan tersebut terdapat beberapa kendala baik dari segi pemasangan, biaya yang tinggi dan dari segi waktu pengerjaannya. Oleh karena itu muncul suatu gagasan untuk mengembangkan penggunaan beton ringan struktural pada bangunan tinggal. Dalam hal ini penggunaan beton ringan yang dikembangkan merupakan beton ringan dengan foam sebagai pelat lantai rumah tinggal.Penelitian ini merupakan penelitian yang berfokus pada perbandingan campuran beton ringan foam terhadap keberhasilan bentuk beton ringan saat pembukaan bekisting 24 jam. Campuran yang digunakan pada penelitian ini yaitu 1:2:0.375 untuk campuran pertama dan 1:1:0.25 untuk campuran kedua. Berdasarkan hasil penelitian ini dari 13 percobaan didapatkan campuran pertama gagal dalam menghasilkan beton ringan foam sedangkan pada campuran kedua berhasil dalam menghasilkan beton ringan foam.Kata Kunci: Beton ringan foam, pelat lantai, campuran.

“…Styrofoam is also used as a substitute for coarse aggregate in making lightweight concrete. Unfortunately, its compressive strength tends to decrease when compared to average aggregate, so it is recommended to use it on non-structural parts, such as partition walls and canopies (Ala & Arruan, 2017;Ginting, 2019;Miswar, 2018;Wibowo & Setiawan, 2019).…”

Purpose: The advantage of lightweight concrete is to reduce the weight, which is considered the dead load on the structure. This study aims to determine the effect of replacing sand with pumice sand as fine aggregate in lightweight concrete. The substitution affects the compressive strength, split tensile strength, and weight. Design/methodology/approach: The research method is through testing in the laboratory, where the test specimens are cylindrical following SNI with a height of 30 cm and a diameter of 15 cm totaling 50 pieces. The composition ratio between regular and pumice sand is 75%:25%, 50%:50%, 25%:75%, and 0%:100%, respectively. Control of the test object using 100% regular sand. Findings: This research shows that adding pumice sand into the mixture decreases the volume weight. The weight of the volume of concrete produced is < 1,900 kg/m3, which is classified as a lightweight one. Research limitations/implications: The resulting compressive strength of 56.63 kg/cm2 decreased against the control test object by 81.10%. At the same time, the split tensile strength is 1.13 kg/cm2, or a decline of 52.05% from the control test object. Originality/value: This paper is an original work. Paper type: Research paper

The purpose of this study was to determine the effect of the use of waste rice husk ash and viscocrete 1003 on the compressive strength and flexural strength of concrete with variations in the mixture of rice husk ash waste 0%, 25%, 30% and viscocrete 1003 0.6%. The results showed that the chemical content of rice husk ash that had been burned was high SiO2 (Silicon Dioxide), which was 75.5 ─ 87.9 % by weight, while the chemical content of unburned rice husk ash was SiO2 (Silicon Dioxide). Which is high that is equal to 86.9 ─ 94.7% by weight. The compressive strength test value of each variation of the specimen which is converted into 28 days of age is for variation 0% the average compressive strength value is 21.590 MPa, for variation 25% with an average compressive strength value of 15.635 MPa and 30% variation with the average compressive strength value is 11.486 MPa. So it can be concluded that the average compressive strength value from the 0% variation to the 25% variation has decreased by 0.05955%, while from the 25% variation to the 30% variation it has decreased by 0.0415%. The flexural strength test value in terms of the maximum average moment on the slab for each variation of the test object converted into 28 days of age is for 0% variation of 146.820 kN.m, for 25% variation of 165.760 Kn.m and variation of 30% of 170.490 Kn.m. So it can be concluded that the average flexural strength value from the 0% variation to the 25% variation has increased by 3.13%, while from the 25% variation to the 30% variation it has increased by 3.36%.
