compressive resistance
1.This crusher is widely used in mining,metallurgical industry,building material ,highway, railway, water conservancy and chemical industries. various material with compressive resistance less than 350 Mpa can be crushed.
2.In Shuikou hydropower station the abrasion-resistant part of ship lock was constructed by using NSF agent and fly-ash mixed concrete. The concrete batched by using 250kg/m3 cement has 86. 3MPa of compressive strength,scour resistance twice as much as that of ordinary concrete,and cavitation resistance four times as much as that of ordinary concrete.
3.A light chemical reaction in the SijN4/Al, Si3N4/Mg interface made the infiltration to be succeeded. The properties of composites,such as compressive strength and wear-resistance,excel greatly the matrix.
4.AZS sintered brick is prepared from fused AZS waste as the principal material, AZS complex binder and zirconite. It possesses high refractoriness under load, high compressive strength. low apparent porosity and high resistance to glass corrosion.
5.Test on the physical|mechanical properties has been made to EMC(earth material catalyst)has indicated that the EMC can effectively raise the compressive strength,shear strength,compactness,loading capacity and resistance to mechanical abrasion of the processed material.
6.The dynamic fatigue behavior was studied for Al_2O_3-ZrO_2 ceramics,and the re-sistance of their slow crack growth was evaluated at room temperature,and the eff-ective factors on slow crack growth of ceramics,were researched. At same time,theeffects of surface residual compressive stress and phase transformation induced resid-ual compressive stress at crack tip were systematically studied on the resistance ofslow crack growth.
7.The results show that the abrasion resistance and compressive property of PTFE/GF increase markedly after irradiating.
8.Abstract: The basic mechanical properties of full mix concrete and its wet-screened concrete incorporating water-reducing agent and air entrained agent tested,such as compressive strength,tensile strength,compressive elastic modulus,tensile elastic modulus,ultimate tensile elongation,flexural characteristics and abrasion resistance,and the relationship of various mechanical properties for the two kinds of concrete is established.The results are important for mass full mix concrete,especially for concrete incorporating air entrained agent.
9.penetration resistance of mortar was investigated in this paper. The experimental results showed that by adding 0.4% and 0.6% GCL1-3A,the compressive strength of the hardened mortar were 145% and 182% of that of control sample. The penetration resistance of the mortar mixing 0.4% GCL 1-3A under water pressure of 0.2MPa was 11 times higher than that of the control mortar.
10.The result shows that the abrasion resistance capability of the aggregate is a little degradation, and that the coarse aggregate coated by powder has a little effects on the mechanic properties of RCC, such as the compressive strength and limiting tensile stress, and on the entrained result of the air-entraining, the anti-permeability and frost-resistance capability of RCC.
