Abstract: In this paper, different polymer dosage in case of early mechanical properties of fly ash slurry, through testing studies have shown that it can increase 7d flexural strength of fly ash slurry in low dosage, result in lower intensity in high dosage. But overall, the compressive –breaking ratio is reduction, polymer can improve flexibility of fly ash cement, it has a certain elasticity and resistance to deformation, in particular, can be used to prevent wind and fire damage for coal road .

Abstract: In this paper, different polymer dosage in case of mechanical properties of fly ash slurry, through testing studies have shown that low-dosage strength of fly ash slurry has increased the role of high-dosage resulting in lower intensity, but the overall pressure off than reduced, improving the flexibility of fly ash cement, is it has a certain flexibility.

Abstract: The reinforced concrete construction of port, wharf, inshore platform etc, which expose in the bad environment, can suffer influence of the corrosion and lower its safety. Particularly with the seawater corrosion, the reinforced concrete construction will suffer to break easily and result a bigness of loss. Therefore, the construction's safe and dependable increasingly become the important problem that study by people. The paper tested the load about 15 experiment columns of reinforced concrete, which are eroded in the artificial seawater corrosion, studied the load changing of reinforced concrete column which in different times of suffering decay. It afforded the basis for analysis the load of reinforced concrete construction in the corrosion environment.

Abstract: With the gob-side entry retaining technology in coal mining project, the materials research of backfill for mine gateway side and development to become the focus of attention. This study is based on the need of Jining well to adopt 42.5R portland cement, Tj-1 early strength agent, Tj-1 super plasticizer, prepared from 8 hours to form removal, 16 hours strength of up to 6.2MPa, 24 hours strength of 12MPa, 28 day strength to 43MPa, and the construction of super-excellent early strength pumping concrete, and obtained satisfactory results through engineering.
