三乙醇胺作为水泥混凝土(早强)外加剂,早在七十年代初就已在我国开始应用,不过当时都是和某种早强剂复合后使用。常与之复合的早强剂有NaCl、Na_2 SO_4、CaSO_4·2H_2 O等。大量试验及实践证明:这些复合早强剂对水泥、混凝土早期强度的建立,都有明显作用。就普通硅酸盐水泥而言,常温同条件下养护3～4天即可达到不掺者28天强度的70％左右。对矿渣水泥也可缩短养护时间。它具有缩短工期的明显优点,对加快施工进度起了促进作用,颇受施工单位欢
Triethanolamine has been used as a cement concrete (early strength) admixture, and it has been used in China since the early 1970s, but it was combined with some early strength agent. The early strength agents often combined with NaCl, Na_2SO_4, CaSO_4·2H_2O and so on. A large number of tests and practices have proved that these composite early strength agents have a significant effect on the establishment of early strength of cement and concrete. For ordinary portland cement, curing at room temperature for 3 to 4 days under the same conditions can reach about 70% of the 28-day strength without additives. Slag cement can also shorten curing time. It has the obvious advantage of shortening the construction period, and it has played a catalytic role in speeding up the construction progress, and it is very popular with construction companies.
