Background technology
Concrete refers to be cemented to gathering materials the general designation of the engineered composite material of entirety by Binder Materials, and it is widely used in civil engineering.Existing concrete, in order to ensure its normal intensity, generally its heavier mass, brings inconvenience to normal construction.Meanwhile, the mobility of existing concrete is poor, and work progress vibrates needs are various, and it not only strengthens difficulty of construction, and easily produces sound pollution.
Summary of the invention
The technical problem to be solved is to overcome prior art defect, it is provided that a kind of lighter weight, good fluidity, it is simple to the lightweight concrete of construction.
In order to solve above-mentioned technical problem, the invention provides a kind of lightweight concrete, including the component of following parts by weight: clinker 500-600 part, sand 170-190 part, perlite 200-220 part, cellulose ether 1-2 part, water reducer 5-7 part, dispersant 1-2 part, water 740-750 part.
As preferably, lightweight concrete includes the component of following parts by weight: clinker 500 parts, sand 180 parts, perlite 200 parts, cellulose ether 1 part, water reducer 5 parts, dispersant 1 part, 740 parts of water.
As preferably, the particle size range of described sand is 130-140 μm, and mean diameter≤136 μm, content >=96% of SiO2.
As preferably, described perlitic particle size range is 160-190 μm, and mean diameter≤178 μm, content >=81% of SiO2.
Present invention also offers the preparation method of above-mentioned lightweight concrete, comprise the following steps:
1), by clinker, sand and perlite mix and blend at least 15min, it is subsequently adding the water stirring 5-8min of half weight portion；
2), it is subsequently adding water reducer and dispersant continues stirring 10-13min；
3), add cellulose ether continuation stirring 10-13min, the water of half weight portion is slowly added in mixture by whipping process.
The beneficial effects of the present invention is: (1), lightweight concrete proportion design of the present invention do not have coarse aggregate, significantly reduces its weight, avoid or reduce the exploitation to sandstone simultaneously, thus decrease the destruction to natural environment；Its mobility is big, is easy to site transport at work progress, it is not necessary to vibrate, reduces difficulty of construction, improve efficiency of construction, reduces sound pollution；(2), coordinated with dispersant by cellulose ether, water reducer, effectively reducing the usage amount of water at the same time, it is ensured that cement high degree of dispersion in concrete, improving the mobility of concrete, it is ensured that the quality of concrete；(3), preparation process of the present invention simple, preparation efficiency is high.
