Well, I have a pretty sill question, I want to start a construction project which deals with construction of different kinds of bricks which are Silicate meaning sand and lime, What I want is to have the knowledge of how to construct them and building techniques.

Where am I?

In TheConstructor you can ask and answer questions and share your experience with others!

Sir, Normally, Calcium Silicate bricks are made up from the addition of lime in sand with suitable amount. Such type of bricks are used for different purposes. It is widely used in construction industries. It is also called as sand lime bricks. It is also used in ornamental work in building and masonry works in building.

Hi, You asked a good question. Well, calcium silicate brakes are generally made up of the sand with line and particularly it is known as a sand-lime brick. basically, in Australian European and African countries, the sand lime bricks are used but in India, it is widely used in a state of Kerala and surrounding areas. to know the manufacturing process of lime silicate place 

please visit a local construction warehouse where you see all and machinery and processes including the manufacturing and get an idea about a manufacturing plant and overall cost of manufacturing. the best way of manufacturing brake uses a locally available material that reduces the cost and increased economy of business.search14 for locally available materials which are suitable for brick manufacturing and try to research on it. This gives you the best result and huge profits.

Sand lime bricks: These are very strong & hard bricks. Sand for these should be coarse (but not very coarse), clean, free from salts or organic matter, with grains of assorted sizes, & well graded so as to have min voids. Lime to be well burnt, free from ashes. It should be a high calcium lime, containing 90-90% of Cal. oxide & not more than 0.5% of magnesium oxide & filled in moulds. The moulded bricks are then placed for hardening in a closed cylinder called Autoclave for 10 hrs. Generally, the bricks are moulded by day & left over night to harden. The lime is slaked & intimately mixed with sand in proportion of 4-10%. Sand-lime bricks are much stronger than clay bricks & are uniform in color & texture.
