DAMPAK PENGGUNAAN AIR BERSUHU EKSTRIM TERHADAP KEKUATAN TEKAN BETON

Abstract

The study aimed to compare the compressive strength and unit weight of normal concrete with concrete using extreme temperature wate, cold water temperature is + 0 °C and hot water temperature is + 100 °C. As a comparison sample used normal concrete using water temperature + 4 °C. The composition of the concrete mix is volume ratio 1:2:3 and the amount of concrete cube specimen every 15 cubes, a total of three kinds of concrete sample; NC, CC and HC. Specimens used were 150 mm concrete cube. Measurement of unit weight using the balance sheet and compressive strength testing using a Universal Testing Machine capacity of 100 tons. The results showed an average unit weight at 28 days of the concrete samples NC, CC and HC, respectively 2151.11 kg/m³, 2210,37 kg/m³ and 2121,48 kg/m³. Average compressive strength at 28 days, respectively kg/m² 106.05, 104.39 and 167.69 kg/m² with a maximum compressive strength of 181.76 kg/m² in concrete using hot water.
