As reinforced material, basalt fiber is added into cement-based material. In this paper, the influence of basalt fiber on the performance of cement-based material is made experiment to look for the more appropriate. The content and length of basalt fiber is the important factors affecting the fluidity, flexural strength and compressive strength.

The application of the gypsum composite concrete made with gypsum - cement - sawdust and additives on the antique architectural Bracket set was studied. Component design, mold making, pouring and conserving concrete of the Bracket set which was made by gypsum concrete, and production process of assembling and installing, construction and installation methods were introduced.

On the basis to clarify the Portland cement hydration mechanism, we have a brief analysis of research methods about Portland cement hydration mechanism, mainly including the hydration heat, ultrasonic method, resistivity method, mercury intrusion method, chemical combine method, CH quantitative measurement, X-ray diffraction method, scanning electron microscopy, providing a theoretical basis of Portland cement hydration mechanism and its material applications in engineering for further study and improvement.
