随着建筑行业的发展，对混凝土提出了更高的要求，高标号自密实混凝土在工程中的应用日趋广泛。作为活性掺合料，硅灰存在收缩率大、价格高等问题。文章研究了超细粉煤灰-微珠替代硅灰加入C70自密实混凝土对工作性和强度的影响规律。
수착건축행업적발전，대혼응토제출료경고적요구，고표호자밀실혼응토재공정중적응용일추엄범。작위활성참합료，규회존재수축솔대、개격고등문제。문장연구료초세분매회-미주체대규회가입C70자밀실혼응토대공작성화강도적영향규률。
With the development of construction industry,higher request for concrete is put forward,high grade self-compacting concrete in engineering application is more and more widely used.As an active admixture,silica fume has high shrinkage rate and price.This paper mainly studies the workability and influence law for strength of ultrafine fly ash-beads to replace the silica fume on concrete.
