    Abstract

    One of the weakness concrete is the concrete has a high density, that is equal to 2400 kg/m3. To lighten the weight of the contents, it is used as a replacement tile fragments of coarse aggregate. The addition of aluminum fibers into the concrete mix aims to increase the value of a absorption of water and impact resistance concrete. This study aims to determine how much impairment absorption of water and impact resistance concrete, as well as the maximum force that can be recovered after the fire with water curing method. This study used an experimental method using laboratory testing is to find the value of a absorption of water and impact resistance concrete pre- and post-burn at a temperature of 500C, as well as the data assigned the minimum time with maximum recovery of strength concrete post-burn. Combustion test specimens made in a laboratory furnace ceramic at Bayat, Klaten. After burned re-treatment with water curing for 28 x 24 hours, 42 x 24 hours and 56 x 24 hours to get the minimum time for maximum recovery. The results of research the water absorption testing uptake at 10 + 0,5 minutes and 24 hours on the concrete without fibers aluminum pre, post-combustion and after re-assigned the treatment for 28 x 24 hours, 42 x 24 hours, and 56 x 24 consecutive hours are 3.468% and 9.096 %; 4.889% and 11.133%; 2.304% and 7.435%; 1.503% and 8.516%; 1.153% and 4.841%. For aluminum fibrous concrete on concrete water absorption value of pre, post-burn and after getting water curing of 4.448% and 11.336%; 5.656% and 12.777%; 2.583% and 10.548%; 2.195% and 11.809%; 5.283% and 9.654%. The impact resistance testresults of concrete without fibers at first crack and collapse in total with the same treatment are 4079.00 4697.03 J and J; 1389.10 J and 1618.65 J; 1536.25 J and 1842.32 A; 2042.44 J and 2254.34 J; 2095.42 J and 2419.15 J. While impact resistance test results of concrete with aluminum fibers are 4585.19 5833.03 J and J; 2183.71 J and 2401.49 J; 2230.79 J and 2572.18 J; 2272.00 J and 2678.13 J; 2260.22 J and 2689.90 J. Based on the above results the addition of aluminum fibers can only improve the impact resistance of concrete. Combustion of the sample results in a decrease in strength due to water evaporation and decomposition concrete at CSH compounds. With water curing is done to improve the quality of the value of water absorption and impact resistance concrete, because the cavities being filled back empty due to the evaporation of water due to combustion and formation of new CSH crystals derived from the reaction of curing water that has not been repeated with hydrated cement in the concrete. Keywords: concrete, post-burn, water absorption, impact resistance, water curing.
