Description
Technical field
The present invention relates to a kind of environment protecting cement mortar with rice husk.
Background technology
General sand-cement slurry regular meeting is according to user's different demands; Like ventilative, waterproof, heat insulation or anti-be full of cracks etc.; Thereby need to add different additives, as adding man-made fiber with the hardness of strengthening the sand-cement slurry moulding and prevent that it is cracked, but the man-made fiber water-repellancy is relatively poor and engages difficult with sand-cement slurry; Perhaps add Baolilong to increase effect of heat insulation and to alleviate the weight of sand-cement slurry moulding, can not cause bad environment pollution but Baolilong a century is mashed, the while Baolilong is not firmer and engage difficult with sand-cement slurry; Perhaps add cement blowing agent (like aluminium powder) in order to increasing effect of heat insulation and to alleviate the weight of sand-cement slurry moulding, but the cement blowing agent water-absorbent by force and not firmlyer also be not durable; Perhaps add chemicaladditives (like silicon) and be used to strengthen the effect of waterproof, anticracking, increase the intensity of sand-cement slurry moulding simultaneously, be detrimental to health but chemicaladditives can discharge objectionable impurities with temperature.
As everyone knows; Rice husk is a crude substance, and many wood materials of processing with discarded rice husk or other wood fibres or wood-plastic composite etc. are arranged, and announces [method for makings of rice husk combination building materials] No. 042468 like the Taiwan patent of invention; Wherein be earlier to use clear water to wash to nearly neutrality after via water retting the rice husk base material; With 80% to 85% of this rice husk, cement is about 10% to 13%, and edible seaweed powder about 2% to 5% and micro-sanitas are mixed water and mixed; It is filled in the mould building materials person who is pressed into different shape through height, yet:
It mainly uses a high proportion of rice husk to make wooden building materials, and the cement of a small amount of ratio increases building materials intensity, but it does not still belong to the cement building material of HS.
Therefore based on the rice husk self character, and the HS of cement itself, rice husk that the investigator attempts adding a small amount of ratio is arranged gradually in cement, to replace many syntheticses.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art; A kind of environment protecting cement building materials composition is provided; It is by adding the rice husk composition to sand-cement slurry; Replace tradition and use chemical additives such as man-made fiber goods Baolilong, thereby increase effects such as HS after the sand-cement slurry moulding, ventilative, waterproof, heat insulation and anti-be full of cracks.
