摘　　要：掺加不同掺合料到海水海砂混凝土中,进行了不同原材料配比、不同养护方式和不同龄期条件下的强度试验,试验结果表明,掺加掺合料后的海水海砂混凝土的强度下降趋势明显延缓,其中掺加矿渣的海水海砂混凝土后期强度增长趋势最为明显,而掺加粉煤灰的海水海砂混凝土后期强度增长量是最大的。The paper undertakes the strength tests on various ratios of raw materials,the different maintenance ways and different ages by adding various mixtures into the seawater and sea sand concrete,proves by the test result that the decreasing strength of the seawater and sea sand concrete is continuing obviously after the mixtures are added,and indicates the increasing strength of the seawater and sea sand concrete with some slag in later period is the most obvious,while the strength of the seawater and sea sand concrete with the fly ash has the maximum increment.
