Abstract
Adhesive Manufacturer adalah cairan tambahan untuk beton yang berfungsi mengurangi pengunaan air ±15-20% serta membuat adukan beton menjadi lebih encer. Selain itu, AM 78 dapat membantu mempercepat proses pengerasan sehingga pengerjaan lebih cepat. Umumnya 1 kg AM 78 digunakan untuk 100 kg-300 kg semen (0,3%-1,2% × berat semen). AM 78 memiliki keunggulan untuk mempercepat pengerasan beton, meningkatkan workability dan mengurangi beton keropos. Pengujian dilakukan di Laboratorium UNISKA MAB Banjarmasin dengan menggunakan metode SNI. hasil penelitian karakteristik bahan telah memenuhi spesifikasi SNI. Komposisi campuran untuk beton dengan AM 78 0 % yaitu semen sebesar 9,29 kg, air 4,83 kg/lt, agregat kasar 1-2 sebesar 21,96 kg, agregat halus 14,64 kg. Campuran untuk beton dengan AM 78 1 % yaitu semen sebesar 9,29 kg, air 4,10 kg/lt, AM 78 0,0929 lt, agregat kasar 1-2 sebesar 21,96 kg dan agregat halus 14,64 kg. Campuran untuk beton dengan AM 78 1,5% yaitu semen sebesar 9,29 kg, air sebesar 4,10 kg/lt, AM 78 sebesar 0,1393 lt, agregat kasar 1-2 sebesar 21,96 kg dan agregat halus 14,64 kg. Campuran untuk beton dengan AM 78 2% yaitu semen sebesar 9,29 kg, air 4,10 kg/lt, AM 78 sebesar 0,1857 lt, agregat kasar 1-2 sebesar 21,96 kg dan agregat halus 14,64 kg. Hasil kuat tekan karakteristik untuk beton umur 28 hari pada material lokal (kalimantan selatan) dengan AM 78 0% didapat kuat tekan sebesar 238,75 kg/cm2, 1% AM 78 didapat kuat tekan sebesar 270,58 kg/cm2, 1,5% AM 78 didapat kuat tekan sebesar 395,64 kg/cm2 dan 2% AM 78 didapat kuat tekan sebesar 222,83 kg/cm2. . Adhesive Manufacturer is an additional liquid for concrete that functions to reduce water usage ±15-20% and make the concrete mixture thinner. In addition, AM 78 can help speed up the hardening process so that the work is faster. Generally 1 kg of AM 78 is used for 100 kg-300 kg of cement (0.3%-1.2% × weight of cement). AM 78 has the advantage of accelerating concrete hardening, increasing workability and reducing porous concrete. Testing was carried out at the UNISKA MAB Banjarmasin Laboratory using the SNI method. the results of the material characteristic research have met SNI specifications. The composition of the mixture for concrete with AM 78 0% is cement of 9.29 kg, water 4.83 kg/lt, coarse aggregate 1-2 of 21.96 kg, fine aggregate 14.64 kg. The mixture for concrete with AM 78 1% is 9.29 kg of cement, 4.10 kg/lt of water, 0.0929 lt of AM 78, 21.96 kg of coarse aggregate 1-2 and 14.64 kg of fine aggregate. The mixture for concrete with AM 78 1.5% is 9.29 kg of cement, 4.10 kg/lt of water, 0.1393 lt of AM 78, 21.96 kg of coarse aggregate 1-2 and 14.64 kg of fine aggregate. The mixture for concrete with AM 78 2% is 9.29 kg of cement, 4.10 kg/lt of water, 0.1857 lt of AM 78, 21.96 kg of coarse aggregate 1-2 and 14.64 kg of fine aggregate. The results of the characteristic compressive strength for 28-day-old concrete on local materials (South Kalimantan) with AM 78 0% obtained a compressive strength of 238.75 kg/cm2, 1% AM 78 obtained a compressive strength of 270.58 kg/cm2, 1.5% AM 78 obtained a compressive strength of 395.64 kg/cm2 and 2% AM 78 obtained a compressive strength of 222.83 kg/cm2. .
