Study on Preparation of High Early Strength Recycled Aggregate Concrete Jian Yin 1,a , Weimin Song 2,b , Yi Chi 2,c and Wei Zou 2,d 1Civil Engineering and Mechanics Institute, Central South University of Forestry and Technology; Changsha; Hunan 410004; China 2Civil Engineering Institute, Central South University; Changsha; Hunan 410075; China acsuyj700930@163.com, bsongweimin0623@163.com, c42054098@qq.com, dstormzou@qq.com Key words: orthogonal design; HSRAC; mix design; water-binder ratio; recycled aggregate; regression model Abstract: 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.
One effective ways of solving the increasing trash concrete is to crash the concrete to aggregates by meeting national standard request and apply them to actual engineering[4-6], which accords with the development direction of green construction materials and gets the prominent society, environment and integrated economy benefit.

Assessment of the Compatibility of Repair Mortars in Restoration Projects CIZER Özlem 1, a, SCHUEREMANS Luc2, b, SERRE Gerty 3, JANSSENS Elke 4 and VAN BALEM Koen5, c 1,2,3,4,5 K.U.Leuven, Department of Civil Engineering, Reyntjens Laboratory, Heverlee, Belgium a Ozlem.Cizer@bwk.kuleuven.be, bLuc.Schueremans@bwk.kuleuven.be, cKoenraad.Vanbalen@bwk.kuleuven.be Abstract In restoration works compatibility requirements of repair mortars are defined based on the original mortar characteristics, but the efficiency and the performance of the repair mortars after application on masonry are not generally evaluated.
These findings are handed over towards the restoration engineer/architect who outlines the repair mortar recipe within the technical specifications to be used by the contractor.
Subsequently a recipe for the repair mortar(s) was prescribed within the technical specification by the restoration engineer/architect and subsequently applied on site.
Interviews with all parties involved (contractor, architect, engineer) were performed to get full information on their experience and their opinion on the compatibility performance of the repair mortars used.
