Sand lime bricks, also known as calcium silicate bricks, are a mixture of sand, lime, and fly ash. Pigments can also be used to add color. The mixture is then molded by applying pressure, which then forms bricks. the materials bind together by a chemical reaction. It takes place when the wet bricks are dried using heat and pressure.
The current types of bricks include lightweight aggregate concrete small hollow blocks, sintered ordinary bricks, sintered porous bricks, autoclaved sand-lime bricks, fly ash bricks, small concrete hollow blocks, hollow bricks, and autoclaved aerated concrete blocks. All the above types of bricks can be made by our brick making machine.
These machines produce approximately 20,000 bricks per hour. Fourthly, the bricks are further coated with a sand coating. There is a continuous, vibrating feeder, which helps coat the brick with soft material. Compressed air or a pressure roller is used for harder materials. As for notably harder materials, the bricks will require sand-blasting.
Flyash lime bricks are chemically bonded bricks manufactured by utilising 80-82% of fly ash, which is a major waste bye-product of pulverised coal fired in Thermal Power Stations, 9-10% of lime, 9-10% of sand and 0.2% of Chemical accelerator (Covered by Central Fuel Research Institute, Dhanbad's patent).

The process of manufacturing fly ash bricks is mainly done by machine. The steps are following-At first, add fly ash at an amount of 57-65%. Fly ash is the fundamental material of this type of bricks. Then river sand or …
Hot steam for hard bricks. The sand lime bricks are hardened by means of steam in hardening chambers (autoclaves). Besides pressing, this is the second most important step in the production of sand lime bricks. The freshly pressed bricks are hardened inside the auto-claves at a temperature of approx. 200° C in an atmosphere
The maximum strength was found for 40% sand – 50% fly ash – 10% lime bricks with 2% gypsum. As bulk utilization of fly ash was the major goal of this investigation, the optimum amount of sand was taken to be 30% that gave a compressive strength of 155.20 kg/cm 2.
Sand-lime brick is a precast building material that simultaneously provides structure, thermal insulation and sound insulation. These bricks are produced by mixing lime, sand, and water into a batch process, where the lime must react immediately with the quicklime to develop some early 'green' strength before entering the autoclave ...

Sand-lime Brick: Sand, fly ash and lime are mixed and molded under pressure. During wet mixing, a chemical reaction takes place to bond the mixtures ...
When comparing the thickness of masonry walls of equal heat resistance but made of different materials, gypsum-based block walls usually have a lower thickness than ordinary clay or sand-lime brick. Even at the same average density gypsum-based walls have lower thickness than walls made of other materials like hollow clay bricks, claydite ...
The principal raw materials for sand-lime bricks are: (1) Sand. It must be free from harmful impurities like chloride, iron oxides, black minerals and organic matter. Sand forms around 90 percent of sand-lime bricks. (ii) …
The hardening process takes about 6–12 h (it depends on the class of bricks, but usually 1 + 8 + 1 pattern means: 1 h of heating + 8 h of autoclaving + 1 h of cooling) [ 6 ]. The traditional sand-lime brick production flow is shown in Figure 1. Figure 1. Production flow of traditional sand-lime bricks.
