Beneficial effects of the present invention are：
（1）The present invention adds polypropylene chopped strand and sulfonation material to can be good at cracking resistance, while using load type active carbon
Slag increases heat insulation effect of the invention and impact resistance；
（2）Byproduct in papermaking waste material white clay system pulp production produced by alkali collection production technology, its main component is
CaCO3.Due to its byproduct CaCO3 In the NaOH containing residual, and NaOH is highly basic, and serious its waste that have impact on makes
With generally as the buried treatment of waste material, waste material is substantial amounts of buried and severe contamination soil, plant is grown, for a long time
Going down will cause the heavy damage of environment, papermaking waste material can be good at turning waste into wealth for manufacturing water reducer, using it
In highly basic pre-treatment is carried out to maize straw so that it preferably can be hydrolyzed in pickling；Produced after maize straw hydrolysis
The material such as cellulose can increase the water-reducing effect of lignin water reducer, while thermal insulation mortar can also be played increase lubrication with
And the effect of increase viscosity, so as to increase the effect of cracking resistance.
(3) cellulosic hydrolysates produced after maize straw hydrolysis are mainly cellulose, hemicellulose, xylose etc.,
Sulfonated cellulose is obtained after sulfonation, sulfonic group and hydroxyl strong hydrophilicity group in sulfonated cellulose can be with by charge attraction
Water forms hydrogen bond, so as to increase hydrophily so that absorption can form one layer of hydration shell in the sulfonated water reducing agent of cement surface, from
