Low-temperature negative-temperature early-strength composite foam light soil and preparation method thereof
The invention discloses low-temperature negative-temperature early-strength composite foam light soil and a preparation method thereof.The low-temperature negative-temperature early-strength composite foam light soil is prepared from, by weight, 275-350 parts of cement, 6-19 parts of composite interface active foaming agent, 1-2 parts of early-strength water reducing agent, 4-7 parts of low-temperature early-strength antifreeze agent, 300-350 parts of additive and 190-210 parts of water. The early-strength composite foam light soil prepared by the invention not only can be normally coagulated and hardened under low-temperature and negative-temperature conditions, but also has quick-hardening and early-strength functions under the low-temperature and negative-temperature conditions, the early strength is increased quickly, the project maintenance period can be greatly shortened, and the construction progress can be accelerated. According to the method, the light soil prepared without additives is good in fluidity, small in apparent density, low in heat conductivity coefficient, small in volume water absorption rate, more stable in heat insulation performance, low in cement consumption per unit volume and lower in cost; and after the addition of the additive, the high-strength-grade light soil with both strength and heat insulation performance can be obtained.
本发明公开了一种低温负温早强型复合泡沫轻质土及其制备方法，本申请的低温负温早强型复合泡沫轻质土，包括以下重量份数的原料：水泥275‑350份、复合型界面活性发泡剂6‑19份、早强型减水剂1‑2份、低温早强型抗冻剂4‑7份、添加料300‑350份、水190‑210份。本发明制得的早强复合泡沫轻质土不仅能在低温和负温情况下也能正常凝结硬化，而且在低温和负温情况下仍具有快硬早强功能，早期强度增长较快，可以大大缩短工程养护周期，加快施工进度。该方法中以无添加料制备的轻质土，流动性好，表观密度小，导热系数低，体积吸水率小，隔热保温性能也更稳定，单位体积水泥用量低，成本也更低；而以加入添加料后则可以得到兼顾强度和隔热保温性能的高强度等级的轻质土。
