| 要旨 | This study investigates the effects of mixture proportions on some properties of "no-fines"previous concrete and evaluates its applicability to control stormwater run-off. Main findings are: a) strengths of previous concrete depend not only on its proportions but also on the curing conditions, b) for any cement content, there is a very narrow optimum range of water-cement ratio that leads to maximum strength, c) the secant modulus of elasticity can be rapidly estimated using ACI 318 developed equation, and d) previous concrete with 15 to 30% voids can practically control the stormwater run-off. |
