Modeling of Aerated Cement Concrete Structure and Increasing its Crack Resistance


Article Preview

In this article is described a problem of increasing crack resistance of aerated cement concrete. Authors, having a model of concrete’s structure, made a disclosure of ratios for calculation of parameters the aerated concrete with disperse reinforcement. These ratios show data about change of structure parameters of aerated concretes with disperse reinforcement such as different density by variation of factors water-cement ratio, percent of reinforcement, ratio between dosing of cement and sand. Concrete’s cracking resistance was evaluated by compressive strength and parameter KIc. As result of experimental data processing authors got regression’s equations, which adequately describe changes of fracture toughness and compressive strength of aerated cement concrete (foam concrete) with density 1200 kg/m3 and 1400 kg/m3 in limits of factor area. There was shown a possibility of two-time increasing of fracture toughness and strength of aerated cement concrete with disperse reinforcement its structure by rough basalt fiber.
