Abstract:Flowing concrete with high flowability prepared with river gravel and crushed stone was investigated for mix proportioning, flowability, strength, shrinkage, carbonation, and freeze-thaw resistance. This concrete has proved highly feasible in terms of cost and performance. The main findings can be summarized as follows: 1) the slump of flowing concrete is capable of sufficiently filling with slight compaction ranges of 24 to 26 cm, corresponding to a flow from 50 to 60 cm, and a differential height less than 8 cm in the box test; 2) flowing concrete with a water-cement ratio from 30 to 60 percent can be made by using a new admixture and with a simple correction of the standard table of mix proportioning; 3) flowing concrete can be produced with specified concrete strengths ranging from 18 to 60 MPa; 4) strength and durability of flowing concrete showed no significant difference from that of AE concrete without any special admixtures.
