Investigation of Compressive Strength of Polymeric Concrete with Rubber Powder and Silica in Different Ages

Concrete is the most important building material that is most used in the construction of various structures including residential buildings, infrastructure structures such as bridges, dams, roads, buildings, docks, dams and other structures. Generally, concrete is made of a mixture of cement with water and coarse aggregates, which in practice are referred to as sand. Determine the amount and weight of each of these materials to build a concrete to obtain the characteristic strength referred to as the concrete mixing scheme. In this study, we investigated the effect of silica and powder on polymeric cement concrete of styrenebutadiene (SBR) found in latex commercial market and for making samples of polymer weight percentages of 10,15 and 20 in cement with alternative 5, 10 And 15% mocrosilica and rubber powder used to replace cement. The results show that the supernatants with the addition of the samples show an increased resistance with the sample and at 42 and 28 days these samples have more than the resistance of the sample. The best resistance in the combination of microsilica and powder was between 6 and 7.5% with a 28-day increase of 15% over the control.
