Studying the effects of coarse pore expanded clay concrete on a permanent formwork made of cement bonded particle boards

Abstract

This paper suggests using a formwork system based on cement bonded particle boards (CBPB) filled with coarse pore expanded clay concrete in order to improve the technical efficiency of the building envelope. Such a structure is made of lightweight or honeycomb concrete units, has a thickness equal to that of heavyweight concrete blocks and provides increased resistance to heat, better fire resistance and longer durability. The relatively modest price of the suggested option is seen as a notable advantage. The effects of coarse pore expanded clay concrete have been shown as being similar to the effects of heavyweight concrete, with the nature of the effects demonstrated on a hydrostatic pressure curve. The author has substantiated the geometric parameters for the suggested heat-efficient envelope design: a 800×800×370 mm block of CBPB filled with coarse-pore expanded clay concrete γ= 500kg/m3.
