Abstract

The invention discloses sisal fiber enhanced coral concrete and a preparation method thereof. The concrete consists of coral concrete and sisal fibers, wherein the coral concrete is in the level C30, and each cubic meter of the coral concrete consists of 315-360 kilograms of cement, 90-135 kilograms of silica fume, 830 kilograms of sand, 716 kilograms of coral and 180 kilograms of seawater; the mass sum of the cement and the silica fume is 450 kilograms. The sisal fiber enhanced coral concrete is prepared by pouring cement, silica fume, sand and coral into an agitating machine for agitating, adding the sisal fibers for uniform dry agitating, and then adding the seawater for agitating. The concrete disclosed by the invention is high in splitting tensile strength and breaking strength, and has the characteristics of energy conservation, environment friendliness, low manufacturing cost, low heat conduction property, zero electromagnetic interference and the like.

Description

technical field [0001] The invention belongs to the technical field of building engineering materials, in particular to a sisal fiber reinforced coral concrete and a preparation method thereof. Background technique [0002] Coral concrete has broad application prospects in island construction and can be applied to flood barriers, roads, airports and other projects in islands and coastal areas. Under the premise of not destroying the local ecological environment, the coral concrete prepared based on coral reef instead of coarse aggregate and seawater instead of fresh water has great practical significance in civil engineering and military engineering. In order to improve the strength and toughness of coral concrete, referring to the example of adding fibers to ordinary concrete, sisal fibers are mixed into coral concrete to improve the basic mechanical properties of coral concrete. [0003] Fiber-reinforced coral concrete is a general term for cement-based composite material...
