Hydraulic Operated Type Semi Automatic Laying Type Concrete Block Making Machine with Automatic Traveling System & Single Vibrator to Mould to produce various types of Solid, Cavity & hollow Cement Concrete Blocks.Fly Ash bricks are made of fly ash, lime, gypsum and sand. The raw materials are blended in desired proportions in a Pan mixer for 4-5 minutes and compressed. They undergo curing for a minimum of 14 days and are then air dried for 7 days. Strength of these bricks can be engineered by varying the compositions.It's commonly used as structural fill for road construction and fly ash can be used to make bricks, ceramic tiles, plaster, Portland cement, and ready-mix cement. Other building materials that may contain fly ash include hot mix asphalt, grout fill, wallboard, concrete pipes, and concrete bricks.Fly ash is most commonly used as a pozzolan in PCC applications. Pozzolans are siliceous or siliceous and aluminous materials, which in a finely divided form and in the presence of water, react with calcium hydroxide at ordinary temperatures to produce cementitious compounds.
