The influence of limestone powder, lithium slag and air-entraining agent on frost resistance of concretes was investigated by freezing-thawing cycle tests. The elastic moduli and weight loss rates of concretes before and after tests were checked. The results show the introduction of limestone powder into concrete is disadvantageous to its frost resistance, which gets worse as limestone powder contents increase. Air-entraining agent used in concrete can improve its frost resistance. The frost resistance grades of concrete containing a certain of air-entraining agent (0.2-0.4‰) can reach F1500, while it is below F300 for limestone powder concrete which is absent of air-entraining agent. The addition of lithium slag into concrete is helpful to frost resistance, and optimum mixing amount is 10%.

Abstract This paper presents the results of an investigation to assess the validity of producing high strength concrete (HSC) using moderate cement content to reduce the consumption of the binders. Cement content is lowered from 500 kg/m3 to 400 kg/m3. The difference in cement content is compensated by the addition of fine limestone (LS) powder. Pozzolans were incorporated as an addition to cement. Different coarse aggregate types were employed. Workability, compressive strength, tensile strength, permeability and drying shrinkage were measured. Test results revealed that HSC with a compressive strength up to 79 MPa (at 90 days age) could be produced with moderate cement content. The mixtures consistency and drying shrinkage are greatly enhanced due to employing LS powder and the permeability is satisfactory. To provide better solution to some concrete disadvantages like cracking and drying shrinkage, using an economic rate for cement are believed to reduce these disadvantages.

With the increasing demand for high strength concrete, more attention has been paid to the problem of high viscosity mixture in high strength concrete technology by academic and engineering circles. This project studied the effects of ultra-fine limestone powder on the workability and viscosity of fresh concrete using the ultra-fine limestone powder (LP) obtained by ultra-fine grinding of limestone powder, building sandstone processing waste, as fine mineral admixture of high strength concrete. The experimental results show that the viscosity of fresh high strength concrete with ultra-fine limestone powder decreases significantly. At the same time, the influence of ultra-fine limestone powder on the strength of the concrete at different ages is very little.
