utilization of phosphogypsum for the preparation of non autoclaved Aerated Concrete
Construction and Building Materials, 2013Co-Authors: Lin Yang, Yun Yan, Zhihua HuAbstract:Abstract Phosphogypsum (PG) was used as raw material for the preparation of non-autoclaved Aerated Concrete, a series of technological parameters, such as water to solid ratio (W/S), quick lime content, steam temperature, and chemical activators, were investigated based on the density and compressive strength of specimens in this paper and the performances of products were also tested. The optimal mix proportion for preparing PG non-autoclaved Aerated Concrete (about 700 kg/m3) is as follows: cement 15%, Ground Granulated Blast Furnace Slag (GGBFS) 30%, PG 55%, quick lime 7%, Na2SO4 1.6%, aluminum powder 0.074%, W/S 0.45. The best steam temperature used for curing the specimens is 90 °C. The compressive strength, frost-resistance and thermal conductivity of products meet the requirements of Chinese autoclaved Aerated Concrete blocks standard, however, the shrinking of non-autoclaved Aerated Concrete is still a challenge and the durability also must be observed in the next work. The results also show that phosphogypsum not only plays the role of filler but also plays the role of activator.

Microstructure and Properties of Silty Siliceous Crushed Stone-lime Aerated Concrete
Journal of Wuhan University of Technology-materials Science Edition, 2006Co-Authors: Wang Qiankun, Chen You-zhi, Li Fangxian, Sun Tao, Xu BingboAbstract:The clayish crushed stone was used for making Aerated Concrete. Through studying hydro-thermal synthesis reaction, mix ratio, gas-forming and performance analysis, Grade-B05 and Grade-B06 Aerated Concrete were prepared successfully. The proper mix ratio and key processing parameters were achieved. The microstructure of Aerated Concrete with crush stone was analyzed by means of XRD and SEM. The experimental results indicate that the hydration products are poorly crystalline C-S-H (B), tobermorite and hydrogarnet. No component of clay was found. Unreacted SiO2 can be in existence, and the structure system of Aerated Concrete is homogeneous and dense.

Experimental Study of Silty Siliceous Crushed Stone-lime Aerated Concrete
Journal of Wuhan University of Technology, 2005Co-Authors: Shui Zhong-heAbstract:This paper reports the study about using of clayish crushed stone for making Aerated Concrete. Through studying hydro-thermal synthesis reaction, mix ratio, gas-forming and performance analysis, B05 and B06 grade Aerated Concrete were prepared successfully. The proper mix ratio and key processing parameters were achieved. The microstructure of Aerated Concrete with crush stone was analyzed by means of modern analysis means such as XRD and SEM. The results indicate that the hydration products are poorly crystalline C-S-H (B), tobermorite and hydrogarnet. The structure system of Aerated Concrete is homogeneous and density.
