Ring Method Test on the early-Age Anti-Cracking Capability of High-Performance Lithium Slag Concrete

Abstract:

Early shrinkage cracking of high performance concrete is a current hotspot of research at home and abroad.In order to make full use of local lithium-slag resources in Xinjiang,We use lithium slag as admixture of concrete to research its early-age anti-cracking capability under low water binder ratio. Ring method test on the influence of the dosage of lithium slag on its early-age anti-crak capability of concrete under the conditions of the same surface area (950m2/kg) and water binder ratio(0.27).We have obtained the best dosages of lithium slag which can resist early-age craking of concrete by monitoring concrete strain and observating concrete cracks. Therefore, the 30%dosages of lithium slag is the best for early-age anti-crack capability of concrete.
