Ready-mixed concrete has gained more and more popularity in the construction projects in China. Long distance or high dislocation pump of concrete mixture is difficult to control the concrete quality , even more worse, the concrete may become drier or stocked during the pumping. How to improve the concretes pump ability is a major concern of the construction company. With the development of civil engineering, the building get much more higher and the bridge get much more longer, the pump ability of concrete matters the final product quality of the structure.

Abstract:
The experiments of compressive strength about maix proportion of concrete are repeatedly done, adopting orthogonal experimental method. In this experiment, dry separation waste rocks and mine tailings in mining slag of Qidashan Iron Mine which is subsidiary company of Anshan Iron and Steel Corporation are used instead of traditional fine and coarse aggregate concretes. Then the optimized mix proportion is determined to make the concrete small hollow blocks. Sample test shows that it is feasible to make load bearing concrete small hollow blocks which can meet national standards.

Combined with the heat-resistant concrete needed for a company combustor, based on the availability of local raw materials, the orthogonal test was used, then by the variance analysis and range analysis, the components of the heat-resistant concrete which could meet the technical requirements of the project were selected. Engineering application results showed: the components of the concrete could meet technical indicators for the engineering application, and effectively reduced the cost of production of heat-resistant concrete.

Abstract:
About 50% of the world's energy consumption comes from the construction industry. At the same time, more than 60% of the raw materials that humans obtain from nature, such as wood, stone, sand, etc., are used to build various buildings. During the construction process, the processing of these materials can cause a large amount of pollution. For example, the production of concrete can cause an increase in greenhouse gas emissions. These phenomena urge us to improve and upgrade building materials to ensure that the basic functions of the building are achieved and its safety is guaranteed on the

Ultrasonic testing of concrete has grown in importance considerably in recent years in non-destructive testing in civil engineering (NDT-CE).

AbstractGlobal CO2 emissions from cement production represent a major challenge on the path towards a future of net zero emissions. Concrete represents 5–8% of the total global CO2 emissions while remaining a critical building material globally. It is imperative to find low-emissions solutions that can reduce the environmental impacts by finding new mixtures and binders for cement production, which are the main contributing factor for emissions from concrete. Alternative concrete binders are being developed, and one such binder is geopolymer cement. Geopolymer cement is made by mixing industri
