Description

technical field [0001] The invention relates to a concrete, in particular to a low-shrinkage concrete and a processing method thereof. Background technique [0002] Most of the concrete used in the traditional construction market is a single structural component. With the increase of building height and the improvement of performance requirements such as earthquake resistance, heat preservation, waterproof, and sound insulation, it has been unable to meet the functional requirements of various parts of use. Contents of the invention [0003] Aiming at the above-mentioned shortcomings of the prior art, the present invention provides a concrete for walls with high structural strength, anti-seismic and anti-stripping and a processing method thereof. [0004] The technical solution of the present invention is: a low-shrinkage concrete, characterized in that: in parts by mass: 10-20 parts of diatomite, 10-20 parts of triethylenetetramine modified durian shells, 5 parts of chest...
