ELABORATION OF BLOCKS MADE ON THE BASIS OF WASTES OF WOOD PROCESSING FACTORIES Е. М. Tsarev, Ren. Kh. Gainullin, P. Е. Tsarev, Rish. Kh.

ABSTRACT Introduction. Today when construction of any building, the problem of choice of walling material by such characteristics as durability, thermal efficiency, and cost arises. In most cases, walling material is a vibro-pressed block, hollow or solid. The blocks can have through and non- through pin-holes. The goal of the research is to elaborate a wall element construction containing less share of expensive materials due to the use of local wood wastes remaining after wood pro- cessing factories activity. The object is a construction of wall non-through block of hollow type (texture - ordinary concrete filled with wood wastes). Result. A building block of hollow type is a cube with non-through internal holes, front connecting surfaces have smooth facial area, upper part of block is solid and has no holes. Inner and base layers in the elaborated construction are interconnected by means of steel framework wooden rods. A comparative analysis of technical characteristics of the elaborated construction with solid blocks showed compliance with the con- struction rules and regulations by weight, void ratio, frost hardiness, index of isolation of airborne noise, water absorption by mass, critical force of destruction. The carried out comparative analy- sis of thermal and physical characteristic of the block (layer width, material density, heat conduc- tivity) showed its advantage over the existing wall blocks. Practical importance. The elaborated construction of the block corresponds to construction rules and regulations, and corresponds to clay brick masonry with the usage of sand-concrete solution. Use of wood wastes for the block makes the production of blocks cheaper. REFERENCES 1. Gorin V.М., Tokareva S.A., Krivopa- lov A.M., et al.
