Study on Mechanical Properties of PVA Modified Cement-based Composites Mixed with Silane Emulsion after Temperature Effect

Abstract This article analyzes the basic performance of PVA modified cement-based composite materials, including mechanical properties, durability, and interface bonding issues. The purpose of this article is to clarify the mechanical properties of the modified material and lay the foundation for further optimization of the material ratio. Therefore, the main points of preparation of PVA modified cement-based composite material mixed with silane emulsion in this paper include testing raw materials, design of material mixing ratio, processing of specimen forming process, determination of slump of materials, pouring and maintenance of specimens, etc. the study. And through the study of the material’s flexural strength, load-displacement curve, material’s compressive strength, material’s toughness index, splitting tensile strength, specimen failure form and other mechanical properties analysis.
