Soil stabilizer and road construction method
The invention discloses a soil stabilizer and a road construction method. The soil stabilizer comprises the following raw material components in percentage by mass: 41-54.7% of sulphoaluminate cement; 13.7%-19.2% of modified ferrochrome slag; 6.8%-8.2% of a cement-based capillary crystalline waterproof material; 1%-2% of redispersible latex powder; 0.8%-2% of a benzene sulfonate surfactant; 0.5%-0.8% of a polycarboxylic acid water reducing agent; 0.3%-0.5% of an early strength agent; 0.3%-0.5% of polypropylene fiber; and 20.5%-27.4% of water. After the soil stabilizer provided by the invention is used for road construction, the compressive strength of a cured roadbed is not less than 2.4 MPa; the CBR value is not less than 19%; the rebound modulus is not less than 1740 MPa, and the technical problem that a stabilized soil roadbed prepared from a soil stabilizer in the prior art is insufficient in bearing capacity and compressive strength is solved.
本发明公开了一种土壤固化剂与道路施工方法，土壤固化剂包括如下质量百分比的原料组分：硫铝酸盐水泥41％～54.7％；改性铬铁渣13.7％～19.2％；水泥基渗透结晶型防水材料6.8％～8.2％；可再分散性乳胶粉1％～2％；苯磺酸盐表面活性剂0.8％～2％；聚羧酸减水剂0.5％～0.8％；早强剂0.3％～0.5％；聚丙烯纤维0.3％～0.5％；水20.5％～27.4％。本发明提供的土壤固化剂用于道路施工后，固化路基的抗压强度不小于2.4MPa；CBR值不小于19％；回弹模量不小于1740MPa，解决了现有技术中土壤固化剂制成的固化土路基的承载能力和抗压强度不足的技术问题。
