Abstract

The invention discloses a hardener of civil material, which comprises the following steps: grinding dehydragent, deicing fluid, impervious agent, sodium silicate, sodium hydroxide, sodium chloride, maleic acid, ferrous sulfate, sodium phosphate, sodium carbonate, anhydrous sodium sulfate, triethanolamine, calcium silicate and quartz sand in the ball mill at 60-120 deg.c; making grinding fineness reach 280-350 order with yellow color; packing; adding cement, calcium lime powder and 2-10 percent composition of last step in the ball mill at 60-120 deg.c; making grinding fineness over 200 order with hoary to obtain the product. The invention possesses high consolidation strength, good water stability and little deformation, which fits for hydraulic and hydroelectric engineering.

Description

technical field [0001] The invention belongs to curing agents, in particular to a curing agent for civil construction materials and a preparation method. Background technique [0002] At present, the cementitious material used in civil construction engineering is mainly Portland cement. This cementitious material uses sand and gravel as aggregate, which has a poor solidification effect on soil and has high requirements on water quality. When sand and gravel are used as aggregate and Portland cement is used as cementitious material to mix concrete, in order not to affect the performance of concrete, in addition to the special requirements for sand and gravel and water quality, the soil in the sand and gravel must be mixed. Clean as much as possible. This is not only time-consuming and labor-intensive, but also in areas where there is no sand or gravel or the water quality is poor, the cost of concrete engineering will increase exponentially. [0003] Our country has a vast ...
