[0002] Traditional cement mortar is made by mixing cement, sand (fine sand or coarse sand) and water. It is used to paint walls, paste tiles / bricks or repair concrete cracks. The Mohs hardness of natural sand is about 2-3 However, limited by the hardness of natural sand, even if the amount of cement used is increased, it is still difficult to increase the compressive strength of cement mortar after hardening. In addition, traditional cement mortar will produce many pores, which are not easy to get rid of after hardening. It will affect the durability of the hard solid mortar, so after a long period of weathering, the hard solid mortar is prone to white blooms, disintegration, cracks, etc., resulting in the peeling of the wall plaster, tiles or bricks

Embodiment Construction
[0017] The invention discloses a mortar composition, which comprises 20-65wt% of cementing material and 35-80wt% of silicon carbide. The mortar composition can be mixed with water to form a mortar, and the mortar can form a hardened mortar after hardening. things.
[0018] Generally, solar panel factories or fabs will produce waste during the chip cutting process, which contains silicon carbide, silicon and cutting oil, etc., and the waste is purified by filtration, separation and other purification steps to remove silicon and oil to obtain silicon carbide. The invention can use silicon carbide recovered from waste as the raw material of the mortar composition, but the invention is not limited thereto, and the mortar composition can use silicon carbide from other sources.
[0019] The cement includes cement, fly ash and furnace stone powder. The cement can be selected from Portland cement. The fly ash is a by-product of a coal-fired thermal power plant collected by an electros...

Abstract
A mortar composition comprises 20-65 wt% of a cementing material and 35-80 wt% of silicon carbide, the cementing material comprises cement, fly ash and furnace stone powder, the mortar composition and water are mixed to form mortar, the mortar forms a hardened mortar after being hardened, and the silicon carbide is used for improving the compressive strength and durability of the mortar hard solid.
Description
technical field [0001] The present invention relates to a mortar composition, especially a mortar composition containing silicon carbide. Background technique [0002] Traditional cement mortar is made by mixing cement, sand (fine sand or coarse sand) and water. It is used to paint walls, paste tiles / bricks or repair concrete cracks. The Mohs hardness of natural sand is about 2-3 However, limited by the hardness of natural sand, even if the amount of cement used is increased, it is still difficult to increase the compressive strength of cement mortar after hardening. In addition, traditional cement mortar will produce many pores, which are not easy to get rid of after hardening. It will affect the durability of the hard solid mortar. Therefore, after a long period of weathering, the hard solid mortar is prone to white blooms, disintegration, cracks, etc., resulting in the peeling of the wall plaster, tiles or bricks.
