| Abstract: | The high strengt h coal-ash concrete that its slump is 190～260mm and its 28days compressive stren gth is 50～75MPa and its leakage-proof gr ade is more than P20 is manufactured in? this experimental research with original? coal-ash of Xinhai Electric factory and? ordinary material．The influence of addi tion amount of coal-ash，binding material? toal amount，sand ratio，water-cement rat io and water reducer of different variet ies and amount on the strength and worka bility of concrete is discussed in this? experimental research．The influence of a ddition amount of coal-ash on leakage-pr oof capability of concrete is discussed． |
