A kind of glass fiber coral sea sand concrete and preparation method thereof

Abstract

The invention provides glass fiber coral / sea sand concrete and a production method thereof and relates to the technical field of marine building engineering materials. The glass fiber coral / sea sand concrete is mainly made with, by volume, 98% of sea sand concrete and 2% of glass fiber, wherein the sea sand concrete is made with a cementing material, coral, sea sand, a water reducer, an anti-freezing agent and sea water. The glass fiber coral / sea sand concrete has the advantages that coral is used as concrete coarse aggregate, sea sand is used as concrete fine aggregate, the materials are taken in situ, and therefore, production cost is lowered and economic benefit is increased; the water reducer is added, and therefore, mixing property and mobility of concrete mix are improved, gaps in the coral are filled with the fine aggregate and the cementing material, hollowness is decreased, and mechanical properties are improved; the glass fiber is added, and therefore, the problems of marineengineering concrete, such as poor durability, proneness to cracking and low corrosion resistance, are solved; the anti-freezing agent helps improve the fiber brittleness problem, and extend the lifeof the concrete.

Description

【Technical field】 [0001] The invention relates to the technical field of marine construction engineering materials, in particular to a glass fiber coral sea sand concrete and a preparation method thereof. 【Background technique】 [0002] With the rapid development of my country's economy, the civil engineering industry has developed in an all-round way in my country. Among them, marine engineering has continuously become the focus of the country's strategic layout of marine resources in recent years. More economical, rapid and efficient construction of marine engineering has become an urgent need in this era. need. Concrete, as one of the most widely used materials in the field of civil engineering, is in great demand in engineering, while traditional concrete materials are too small in marine engineering reserves, which cannot meet the needs of marine engineering, and the cost of inland transportation of traditional materials is comparable Therefore, coral and sea sand, whic...

Problems solved by technology

[0005] The Chinese patent with the application number CN201410388709.3 disclosed a carbon fiber coral concrete and its preparation method on November 19, 2014, including carbon fiber coral concrete and its preparation method. The addition of carbon fiber in the concrete enhances its crack resistance. However, compared with glass fiber, the cost of carbon fiber is relatively high, and the economy is low. Moreover, due to the brittleness of carbon fiber material, it is easy to cause damage to the fiber during the preparation process, so that the normal function of the fiber cannot be guaranteed.
