Experimental Study on Improvement of Compressive Strenght of Concrete Using and Durability of Concrete of Specified Concrete with Adding Waste Spent Fire Brick, Granite and Marble

The advancement of concrete technology can reduce the consumption of natural resources and energy sources and umpteen varieties of concretes (FAC, HVFAC, FRC, HPC, HSC, and others) were researched in several laboratories and brought to the field to suit the specific needs. Marble, granite and Spent Fire Brick industry has grown significantly in the last decades with the privatization trend in the early 1990s, and Accordingly, the amount of mining and processing waste has increased. Stone waste is generally a highly polluting waste due to both its highly alkaline nature, and its manufacturing and processing techniques. The objective of this paper is to utilize waste marble, granite and Spent Fire Brick waste of different sizes in the manufacturing of concrete bricks, with partial replacement of conventional coarse and fine aggregates with Marble, Granite and Spent Fire Brick waste content up to 25%.and design mix is m40 The produced bricks are tested for physical and properties according to the requirements of the American Standards for Testing Materials (ASTM) and the IDIAN Code . These tests were carried out to evaluate the mechanical properties for 7 ,14and 28 days. .150mmx150mx150mm cubes The test results revealed that the recycled products and Reuse of this kind of waste has advantages economic and environmental, reduction in the number of natural spaces employed as refuse dumps.
