Fly Ash bricks are made of fly ash, lime, gypsum cement and sand. These can be extensively used in all building constructional activities similar to that of common burnt clay bricks. The fly ash bricks are comparatively lighter in …

the study that the replacement of normal clay bricks with Fly ash bricks can be done effectively to increase quality of structures. Key words: - Fly Ash, Fly ash bricks, Water Absorption, Compressive Strength. 1. INTRODUCTION A large amount of Fly ash is obtained as waste material thermal power plants. It is generated as by-product

 — The bricks used in building construction are manufactured from fly ash, agro-forestry wastes, construction & demolition wastes (C&D), ground granulated blast furnace slag (GGBFS) using NaOH as activator in order to provide compressive strength in the range of 3-6 MPa with ambient curing at 30 °C for 28 days.

 — Researchers evaluated the environmental and thermal performance of innovative fly ash-based bricks incorporating agro-forestry and construction waste. Activated with sodium hydroxide, these bricks exhibited lower CO2 emissions and superior thermal insulation compared to traditional burnt clay bricks.

 — The compressive strength, unit volume weight, water absorption and thermal conductivity of the fly ash–sand–lime bricks obtained under optimum test conditions are 10.25 MPa, 1.14 g/cm3, 40.5%...

 — The thermal conductivity 'k' values of 0.40–0.45 W/m K, of fly ash bricks results in better thermal insulation as compared to burnt clay bricks ('k': 0.8 W/m K) which may lead to thermal...

The objective is to reduce the thermal conductivity of bricks and find optimal composition of fly ash bricks so that the cooling and heating of the building can reduce and as well as the waste product (corn husk) can also be utilized. The composition of fly ash bricks is fly ash, sand, and cement.

Thermal Conductivity is a capacity of heat to store in material, the determination of thermal conductivity of a material is not simple since it may involve the measurement of a very small heat flow and the maintenance of steady temperatures over considerably long periods.

1. PRODUCT DESCRIPTION. The aeration is caused by a mix of various materials mainly consisting of fly ash, quicklime, cement, gypsum, aluminum powder and performance additives mixed with water in a high-speed mixer. not be more than the maximum permissible limit.

 — Thus, the clay brick-making industry contributes to greenhouse gases directly affecting soil fertility. The primary focus of this review article is to promote research on flyash-based bricks for the brick industry and provide safe and cost-effective sustainable materials to substitute clay bricks.
