Effect of Rice Husks Concrete Preformed Coffers and Bricks Use on Building Structural Elements

This article highlights the effect of rice husks concrete preformed coffers and bricks use on building structural elements (joists, beams, columns and footings). For this purpose, 15 cm thick of preformed coffers, hollow and solid bricks are made from cement - rice husks, cement - rice husks - sand and sand –cement mixtures to determine their characteristics: density, surface weight, brick compressive strength and preformed coffer bending strength. These characteristics were used to calculate building structural elements (joist, beam, column and footing). The results show that the preformed coffers and bricks of rice husks concrete are lighter than those made of sand - cement mortar. The compressive or bending strengths of these elements are similar. The use of rice husks concrete preformed coffers reduces dimensions and reinforcing steels of building structural elements.
