High temperature effects in concrete, mineral additive variation of varieties

In this study, the effect of high temperature mineral admixture in concrete according to the types of change were investigated. For this purpose, cement CEM I 42.5 R and % 0% 10%, 20%, 30%, 40 joined as a substituted barite powder, diatomite, silica fume, fly ash is used as the different minerals. TS802 in accordance with 600 pcs 10 * 10 * 10 samples were produced. These are pools of lime saturated cycles after waiting 28 days 200, 400, 600, and 800 ° C were exposed to high temperatures. In addition, mineral reinforced concrete specimens with a 28-day strength, dry unit weights, weights and saturated weights were underwater. Detected in the percentages of water absorption by weight of the concrete compressive strength of the samples were then made measurements of PGH. Experimental results show that the compressive strength of concrete exposed to high temperature changes that occur are analyzed according to the type of mineral additives.
