Abstract

The invention relates to the field of building materials, in particular to a non-cement-based sandy arsenic rock unburned brick effectively utilizing arsenic rock and used for controlling water and soil loss of the arsenic rock and a preparation method thereof. The brick is prepared from the arsenic rock, an active blending material, an activator and water, a main material, the active blending material and the activator are weighed by weight and put into a cement paste mixer to be mixed and stirred uniformly, then water is added, stirring is carried out for 90 seconds, pressure molding is carried out after uniform stirring is carried out, the wet density of a molded module after forming and demolding is no less than 1950 kilograms per cubic meter, maintenance is carried out for 28 days ina natural state, and the non-cement-based sandy arsenic rock unburned brick of which the compressive strength is 10-20 MPa is obtained.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a non-cement-based sandy sandstone burn-free brick that effectively utilizes the sandstone and is used for controlling soil erosion of the sandstone and a preparation method thereof. Background technique [0002] Existing unfired sandstone bricks all use cement as the main material. This kind of unfired brick has complicated maintenance conditions and narrow application fields. At the same time, the main raw materials for making cement are limestone and clay. The production of cement not only consumes a lot of land and other resources and energy, and pollute the environment at the same time. Therefore, in recent years, governments at all levels have strictly controlled the production of cement and closed down a large number of cement manufacturers, causing the price of cement to soar. improve. Contents of the invention [0003] The purpose of the present invention is to overc...
