The Fuzzy Evaluation of Compatibility between PC-HPWR Agent and Cement Fan Wanga, Shansuo Zhengb and Xiaofei Wangc School of Civil Engineering, Xi’an University of Architecture and Technology, Xi’an, 710055, China aship_wang2955@sina.com, bzhengshansuo@263.com, cwangxiaofei870102@163.com Key words: fuzzy evaluation; compatibility; polycarboxylates high performance water-reducing (PC-HPWR) admixture; reference cement Abstract: To evaluate the compatibility between polycarboxylates high performance water-reducing admixture and cement, the initial Marsh-time or fluidity(T), loss rate of fluidity as time(FL), saturation point(P), setting time(ST) and bleeding rate(R) are considered simultaneously.
Marsh cone-using method(standard method) and cement paste fluidity test method(alternative method) are commonly used to indicate the detection of the compatibility between water-reducing agent and cement in engineering application.
However, it is far from enough to instruct specific engineering application only with the recommended indicators for the reference cement.
Fig. 1 Frame sketch of the fuzzy comprehensive evaluation model Fuzzy evaluation for compatibility based on the program Matlab Demands The reference cement used in test is in accord with the engineering requirements interrelated with appendix A by the GB 8076-2008 of china standard.

In spite of water deficient in China, a lot of groundwater is drained in dewatering engineering every year.
Although there should be recharge for the drained groundwater of dewatering engineering as required, all enterprises discharge the groundwater into sewage conduit for saving costs.
As indicated by practical engineering, this new technology is very suitable for standard layers of high-rise buildings.
