Characterization of Pozzolanic Reaction and Its Effect on the C-S-H Gel in Fly Ash-cement Paste被引量：1
《Journal of Wuhan University of Technology(Materials Science)》2011年第2期320-325,共6页王磊 何真 
Funded by the National Basic Research Program of China (973 Program)(No. 2009CB623201);the National Natural Science Foundation of China (No. 50972109);the Doctoral Program of Higher Education (No. 20090141110021)
High resolution solid-state 29Si MAS NMR,combined with XRD,SEM and FTIR were used to characterize the pozzolanic activity of FA,type of main pozzolanic reaction products,and the effect of pozzolanic reaction on the C-...

Probing the hydration of composite cement pastes containing fly ash and silica fume by proton NMR spin-lattice relaxation被引量：6
《Science China(Technological Sciences)》2010年第6期1471-1476,共6页SHE AnMing & YAO Wu Key Laboratory of Advanced Civil Engineering Materials (Tongji University),Ministry of Education,Shanghai 200092,China 
supported by the National Basic Research Program of China (973 Program) (Grant No. 2009CB623105)
Proton NMR spin-lattice relaxation (T1) was used as a prober for observing the hydration process of composite cement pastes blending fly ash and silica fume during the early age.The distribution at initial time,evolut...

Methods of Modifying the Brittle Behavior of Cementitious Composites被引量：1
《Journal of Wuhan University of Technology(Materials Science)》2010年第1期156-161,共6页庞超明 LEUNG Christopher KY 
Funded by National Basic Research Program of China (973 Program) (No. 2009CB623200);Hong Kong Research Grant Council under CERG 616405
We put forward effective methods of increasing the tensile strain of cementitious composites with 2% PVA fiber and high fly ash content. The test results show that curing condition has a significantly effect on the te...

Prediction of compressive strength of cement mortars with fly ash and activated coal gangue被引量：5
《Journal of Southeast University(English Edition)》2006年第4期549-552,共4页周双喜 陈益民 张文生 
The National Basic Research Program of China (973Program)(No2000CB610703)
The pozzolanic activity of coal gangue, which is calcining at 500 to 1 000 ℃, differs distinctly. The simplex-centroid design with upper and lower bounds of component proportion is adopted to study the compressive st...
