| description | Fine-grained modified concrete, reinforced with polyvinyl chloride fiber, is an innovative material, the production of which is at the development stage in Russian construction. Polyvinyl chloride fiber has high technical characteristics, is not prone to corrosion and is absolutely neutral to the environments that are created during the hardening of concrete and the operation of products, and also does not affect the nature of the hardening of the binder. The article presents the results of scientific research aimed at developing the basics of methods for predicting the properties of products, as well as choosing and optimizing the costs of the main raw materials. The conducted active experiment and the processing of its results made it possible to obtain regression equations for the compressive strength of fiber-reinforced concrete, as well as its average density, depending on variable factors. So, to obtain fiber-reinforced concrete with a compressive strength of 46.5–47.5 MPa; with an average density of 1668–1674 kg / m3, Portland cement with an activity of at least 45 MPa should be used; at a PVC fiber consumption of 5.9–6.0 kg/m3, a plasticizer consumption of 7.6–7.8%, as well as a consumption of finely ground construction waste 673–676 kg/m3. Based on the results of an active experiment, their statistical and analytical processing, the basics of the method for selecting the composition of fiber-reinforced concrete, depending on the specified values of variable factors, have been developed. |
