Abstract
The invention discloses a compound clay brick formula and relates to the field of building materials. The compound clay brick formula is prepared from lime, quartz sand, sand, fine sandstone, Al2O3, SiO2, CaO, Na2O, K2O, P2O5 and a small amount of V and Ti. The raw materials are prepared into half-dry pug according to the formula, pressed into a brick shape in high pressure and roasted into clay bricks under about 1400 DEG C; comprehensive mechanical property of the clay bricks is obviously improved, and service life of the clay bricks is improved.
Description
technical field [0001] The invention relates to the field of building materials, more specifically, the invention relates to a formula of composite clay bricks. Background technique [0002] Clay bricks are artificial small blocks used in construction. The existing clay bricks use clay as the main raw material and are formed by mud treatment, molding, drying and roasting. There are solid and hollow ones. The formula of existing clay bricks is relatively traditional, and most of them are made of powder materials such as shale and coalgangue. The produced clay bricks have general mechanical properties, poor strength and short service life. Contents of the invention [0003] The problem to be solved by the present invention is to provide a formula for composite clay bricks. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a formula of composite clay brick, characterized in that, the formula of the composite clay bric...
