Recycled Aggregate Selfcuring Highstrength Concrete

Ductile Evaluation and Mechanical Performance of Recycled

In recent years, a high toughness cement composite material (HTCCM) has been developed, which has far more performance than existing fiber reinforced concrete. HTCCM is a composite material made by reinforcing cement-based materials with fibers. It exhibits multiple crack characteristics under bending stress and greatly improves toughness during flexural, tensile, and compressive fracture.

Effects of recycled concrete aggregate on some mechanical

Aggregate is one of the essential ingredients for creating concrete, as it generally comprises 75% of the total for any concrete mixture. The strength of the concrete product is thus generally determined by the characteristics of aggregates used, which explains the need for a choice of alternative coarse aggregates. The goal for this study is to determine the strength properties of recycled

Wood waste makes recycled concrete stronger than ever

Concrete is made by mixing an aggregate such as gravel with water and cement. Once the mixture has cured, the cement hardens, and binds with the aggregate to form a solid block of material.

Study on Preparation of High Early Strength Recycled

An orthogonal experimental design method was adopted for the mix design of high early strength recycled aggregate concrete (HSRAC), and the influence of water-binder ratio, percentage of recycled aggregate(RA)and highly active compound mineral admixture (HACMA) content on the strength of the concrete was discussed. The test results indicated that water-binder ratio was the most principal and
