Abstract
Based on appropriate assessment methods and indexes of self-compacting concrete proposed, properties of concrete made with river-sand and machine-made sand was firstly compared in different mix proportions. The techniques such as basic parameters optimization of mix proportion, admixture composition, large-volume mineral admixtures addition for preparing machine-made sand self-compacting concrete (MSCC) were proposed, and effect of different factors on workability and compressive strength of MSCC was studied. The results indicate that requirements on parameters of mix proportion for MSCC are different from those of river-sand self-compacting concrete. Applying the techniques such as basic parameters optimization of mixture, admixture composition, high-volume mineral admixtures addition, MSCC with initial slump above 24cm, slump flow over 60cm, delivery time of inverted slump cone (DTIS) between 5s and 15s, compressive strength above 60MPa at 28 days was prepared.
