mixing proportion
1.Mixing Proportion Selection and Temperature Control of the Concrete of the Later?pouring Blocks of Anchorage in Haicang Bridge
2.Practices show that the compressive strength, the modulus of elasticity, the permeability coefficient and the compactness of concrete obtained respectively by the compaction method, the unconfined compression static compaction method, the sand trenching and filling method, and nuclear densimeters meet the requirement of design, and the mixing proportion of concrete of the side-wall is reasonable.
3.Iron matrix graphite composite was prepared by mixing different proportion of grey iron wafer and graphite(1%,2%,3% and 4%),compacting and sintering. The best graphite content is 2% though the analysis on the microstructure,hardness and wear resistance. The feasibility and developing prospect of the application of the material on colliery vertical shaft tin guiding bush are discussed.
4.The in-fluence of organicsilicone parent molecule,mixing ratio of acrylic monomers,proportion of acrylic ester and silicone polymer and charging process to copolymer perfo rmance are discussed.
5.A new type of concrete admixture is fabricated by mixing lithium salt residue (LSR) and fly ash in a certain proportion.
6.After 90d mixing with soil, with treatment of Pb(NO3)2 and PbO, the proportion occupied by Pb2+ could be high reaching 75.23%, and related with lowering of pH value and DOC content of the soil solution.
7.An auxiliary medium was made by mixing shredded waste tyres,ethylene vinyl acetate(EVA) copolymer and zeolite in certain proportion and added into aerobic zone of A2/O process to investigate the influence on nitrogen removal efficiency.
8.Based on the isotopic compositions of samples and their distribution characteristics on the _(Nd)-T, (~(87)Sr/~(86)Sr)_i-T, and _(Nd)-_(Sr) diagrams, these granitoids of syntexis series are considered as mixing products of upper crust end-member and depleted mantle end-member in certain proportion.
9.After compound of spontaneous combustion gangue powder and fly ash, that water demand of gelled material systems is decreased than that of only mixing spontaneous combustion gangue powder and the tendency of water demand is gradually increasing with the increment of the proportion of spontaneous combustion gangue powder in powdery materials.
10.The optimized conditions were found as following: 1% TiOPc as sensitizer, 0.5% TN7F as electron transport material, a proportion of CGM:CTM:PC1:80:120 and a mixing solvent of TIfF and dioxane.
