Abstract:In many parts of the world, the lowest temperature in winter is less than -20 degrees Celsius. It is an important problem in the field of construction engineering to improve the quality of concrete engineering and improve the durability of the structure under extreme climate. This paper introduces the development of ultralow temperature anti freezing pumping admixture. In the experiment, the concrete cured at -4°F (-20 °C) or -13°F (-25°C) for 7 days. And then the specimens were maintained in standard condition for different ages. Mechanical and durability properties of concrete were test in different curing conditions and different ages were studied. Mechanical properties include “negative temperature” compressive and flexural strength. Durability includes anti-permeability performance, dry shrinkage and chloride ion penetration resistance. The experimental data shows that the concrete have good mechanical and durability properties in ultra-low temperature because of the addition of an anti-freezing pumping agent. Compared with ordinary antifreeze, the negative temperature strength of concrete mixed with this ultralow temperature anti freezing pumping agent can be increased by more than 100%. By means of scanning electron microscopy (SEM) and pore size analysis were carried out. The action of this super low temperature anti freezing pumping agent and the frost resistance mechanism of concrete are analyzed.
