(Ⅱ) --Pore ratio and compressive strength Abstract: This study was focussed upon the porosity (pore ratio) and compressive strength of the raw material, which was mixed... and compressive strength were measured, and were compared with those of the compacts un roasted. The results show that, the porosity of all compacts decreases with increasing pressing pressure linearly......
18 June 2013 Abstract: The effect of Sn, Ca, Al, Si and Zn addition on the compressive strength of cast Mg-Sn-Ca (TX) alloys was studied in the temperature range of 25-250 °C and correlated... in the matrix. While the compressive strength decreases with the increase in temperature, for Sn/Ca up to 2.5, a plateau occurs in 100-175 °C, which is attributed to the strengthening by Mg2Ca. However......

Institute, Gansu Academy of Sciences, Lanzhou 730000, China) Abstract: To discuss the effect of salt content on compressive strength, the unconfined compressive strength test for sulphate saline soil......
high-volume fly ash (HVFA) is usually used to obtain economical and more sustainable merits, but these merits suffer from dramatically low compressive strength especially at early ages. In this work, the possibility of using micro-size metakaolin (MSK) particles to improve the compressive strength of HVFA paste before and after subjecting to high temperatures was studied. To produce HVFA paste......

The microstructures of the Mg-Sn-Pb alloys consist......
Improvement of the Compressive Strength of Carbon Fiber/Epoxy Composites via Microwave CuringXuehong Xu1,Xiaoqun Wang1,Qun Cai2,Xu Wang2,Ran Wei1,Shanyi Du11. School of Materials Science... for improving the compressive strength of the materials. By controlling the power of microwave heating, vacuum bagged laminates were fabricated under one atmosphere pressure without arcing......
Effects of binder strength and aggregate size on the compressive strength and void ratio of porous concreteP. Chindaprasirt1,S. Hatanaka2,N. Mishima2,Y. Yuasa3,T. Chareerat41. Department of Civil... aggregate. The general equations for porous concrete are related to compressive strength and void ratio for different binder strengths and aggregate sizes.关键词:......
such as hardness and compressive strength were investigated. The optimum density (93.33%) was obtained at the compaction pressure of 6.035 MPa. Scanning electron microscopic (SEM) observations of the microstructures... specimens and resulted in no beneficial effect on the strength and hardness. The compressive strength and hardness of Ti64 alloy/5% nano SiCp MMCs showed higher values. Hence, 5% SiCp can be considered......
of Metallurgical Science and Engineering, Central South University, Changsha 410083, China) Abstract: Based on the analysis of the leaching toxicity and compressive strength, the sulfuration slag and gypsum slag... of sulfuration slag is less than 150 μm, the gypsum slag adding ratio is 20% and the aggregate adding ratio is 15%, and the compressive strength of solidified body will reach the maximum value as 47.5 MPa......
