Abstract

A fine improved wood belongs to the field of building materials. The constituents and weight percentages of the wood are as follows: 10-40% of natural sand, 10-40% of machine processed sand and 20-60% of industrial residues. The wood also comprises gravels with content not more than 54% and 0.003-0.5% of alkali organic compound. The fine improved wood can be obtained by evenly mixing the above constituents in a mixer. The fine improved wood can effectively inhibit alkaline-aggregate reaction of concrete, improve the strength of concrete, have excellent effects on passivation, anti-corrosion and protection of reinforcing bars and prolong lives of buildings. The fine improved wood is mainly used as mortar materials, foundation improve wood, light-weight concrete aggregate, concrete precast elements and sewer fillers, and can also be used as vegetation soil improved wood.

Description

【Technical field】 [0001] The invention relates to a mortar material, a ground improvement material, a lightweight concrete aggregate, a concrete prefabricated part material, and a sewer filling material, and belongs to the field of building materials. 【Background technique】 [0002] With the development of society, the requirements for modern architectural modeling and architectural design are getting higher and higher. At the same time, many conditions have been put forward for the concrete building structure itself. However, in practice, we have also found that the biggest defect of concrete is that it is easy to crack. These cracks are constantly generated and expanded under the external physical and chemical effects, causing concrete carbonation, peeling off of the protective layer, and corrosion of steel bars, which weakens the strength of concrete and reduces its durability. In severe cases, collapse events even occur, endangering the normal use of the structure. Ther...
