Abstract

Pengaruh penambahan gula aren terhadap ketahanan mortar yang akibat suhu tinggi 250oC, 500oC, 750oC selama 3 jam dengan menggunakan furnace. Pembuatan benda uji menggunakan mortar dengan ukuran sisi 5 cm. Pengujian dilakukan setelah mengalami perawatan kering pada suhu kamar selama 28 hari. Setting time dan kuat tekan menggunakan kadar gula aren 0%, 0.1%, 0.3% dan 0.5% dari berat semen. Kuat tekan yang tersisa setelah dipanaskan pada suhu 750oC untuk dosis gula aren 0%, 0,1%, 0,3% dan 0,5% adalah 39%, 58%, 54%, 51%. Dosis gula aren 0,1 % bersifat retarder dalam campuran pasta semen karena terjadi penundaan waktu ikat awal 5,12 x (495 menit) dibandingkan tanpa bahan tambah gula aren. Dosis gula aren 0,3 % dan 0,5 % cenderung bersifat accelerator karena waktu ikat awalnya lebih cepat dibandingkan tanpa bahan tambah gula yaitu 0,74 x (71,25 menit) dan 0,75 x (72,50 menit).

Abstract

The study was conducted to determine the effect of increasing the water content of 2.5%, 5%, 7.5% and 10% of the effect of adding water-cement ratio to the modulus of elasticity of concrete with the Ultrasonic Pulse Velocity/ UPV test. This research was carried out using fine aggregate type 1 sand from Cimalaka, maximum diameter of coarse aggregate 20 mm from Cimahi and Portland cement Type 1. Each test uses two samples. The results of the analysis show that the addition of water will reduce the value of the modulus of elasticity.
