Coral reef sand strengthened material and using method thereof

Abstract

The invention provides a coral reef sand strengthened material and a using method thereof. The coral reef sand strengthened material consists of 100 parts of water, 1 part of polyacrylamide, 20-25 parts of water-soluble thermosetting glue, 5-10 parts of a polyvinyl acetate emulsion and 50-100 parts of cement, wherein the water-soluble thermosetting glue can be one selected from phenolic resin or acrylic resin. The manufacturing method and using method of the material are simple, the preparation raw materials are easy to obtain, the cost of strengthening treatment on coral reef sand is low, andthe material is convenient to use in islands and coastal areas. Through the adoption of the strengthened coral reef sand, the strength of cement mortar or concrete prepared by the coral reef sand isobviously improved, and chloride ions contained in the coral reef sand can be effectively prevented from diffusing to the outside, so that the corrosion probability of steel bars in coral reef sand concrete is reduced, and meanwhile, the fluidity of the mortar or the concrete prepared by the coral reef sand is also improved.

Description

technical field [0001] The invention relates to a coral reef sand strengthening material and its application method. Background technique [0002] Coral reef sand contains a lot of porous particles, and its particle strength is lower than that of ordinary river sand or mountain sand. Correspondingly, the strength of mortar or concrete prepared from it is also lower; coral reef sand is also easy to absorb water, resulting in its mortar, The fluidity of concrete is reduced; at the same time, coral reef sand contains high chloride ions, which will erode the steel bars in concrete, so it cannot be applied to structural concrete containing steel bars, which seriously restricts its application in construction projects. [0003] In recent years, the country has added a lot of infrastructure projects in coastal and island areas. These areas usually have rich coral reef sand resources but lack river sand or natural mountain sand. In fact, most coral reef sand producing areas lack riv...

AI Technical Summary

Problems solved by technology

However, due to the limited effect of water washing to eliminate chloride ions, it is difficult to clean the chloride ions, and many coral reef sand resources lack fresh water, especially the fresh water on many islands is extremely precious, so the "water washing" method is very important for coral reef sand. It is rarely used in dechlorination treatment
