High-strength concrete is one of the various special concretes that have become increasingly popular in recent decades. offers a higher strength-to-volume ratio than normal-strength concrete. However, design provision not explicitly served most building codes. This study focuses on shear strength high-strength and many factors influence strength, i.e., longitudinal reinforcement ratio. The was ...

This paper discusses the state of art in research on use textile-reinforced concretes structural maintenance. Textile-reinforced can be used maintenance for various purposes, including sealing and protection existing building structures, as well strengthening structures. The first-mentioned aspects are explained this basis example applications. A special focus is placed heritage-protected devel...

In the construction industry, cement concretes are most widely used building material. New generation materials with increased strength and durability in of critical facilities. Special requirements imposed on such to ensure their quality. The issues control quality powder-activated a new at stage preparation constituent components considered. Author made article analysis classifier data for de...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

Properties are provided for submicron aluminum oxide developed in SAO PKF NK low-cement refractory concretes, and also the LCRC of aluminosilicate composition obtained. It is demonstrated that properties concretes prepared on basis alumina no worse than domestic imported analogs.
