TABLE 1 physical Properties index
The performances of comparative examples 1 to 4 and examples 5 to 7 in a low-temperature environment were tested by using GB/T50082-2009 standard for testing the long-term performance of ordinary concrete and GB50164-2011 standard for controlling the quality of concrete, and the test results are shown in table 2.
TABLE 2 comparison of Performance at Low negative temperature
As can be seen from tables 1 and 2, in comparison with comparative examples 1 to 4, the initial slump of the portland cement, sulphoaluminate cement, aluminate cement and the admixture compounded in examples 5 to 7 according to a certain proportion is obviously increased, the slump is well maintained, the hour strength is obviously improved, and the later strength is continuously increased. Meanwhile, the retention rate of the low-temperature frost resistance of a system compounded by various kinds of cement is higher, which shows that the low-temperature resistance is stronger. The reason is that compared with sulphoaluminate cement or aluminate cement, the ordinary portland cement has slower setting time, and plays a role of delaying in the initial stage when compounded to a certain proportion, so that the initial slump is larger, and the initial slump is kept relatively better; with the continuous deepening of hydration reaction, after the three kinds of cement and the admixture are compounded, the following reaction can be quickly carried out:
3CaO·3Al2O3·CaSO4+2CaSO4+38H2O＝3CaO·Al2O3·3CaSO4·32H2O+2(Al2O3·3H2o); a certain amount of high-sulfur hydrated calcium sulphoaluminate, namely (ettringite) and alumina gel, is generated, and the early strength is greatly improved. The hydration of the water reducing agent, the antifreezing agent, the retarder, the coagulant and the like to the cement minerals of the composite system is enhanced, the quantity of formed ettringite and alumina gel is increased along with the continuous deepening of the reaction, the reaction speed is accelerated, and the early strength is obviously improved. Meanwhile, the strength skeleton which generates ettringite in the early stage is filled with colloid, so that the structure of the cement stone is compact, the porosity is reduced, the later strength is improved, and the impermeability and frost resistance are further enhanced.
