Experiments were conducted outdoors during the summer of 2014 in Abu Dhabi. The slump flow and rheological properties of SCC incorporating various types of supplementary cementitious materials (SCMs) were examined under such types of harsh environmental conditions. A portable concrete rheometer (BT2) was used to measure the rheological properties of the investigated SCC mixtures. In this study, the neural network technique was employed to predict the rheological properties of SCC under hot weather conditions and prolonged mixing. The ambient temperature, mixing time and SCMs were the network input parameters. The relative viscosity, relative yield stress and slump flow were the output parameters. The optimum network architecture was selected based on Akaike information criterion and mean absolute percent...","PeriodicalId":51787,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Construction Materials","volume":"21 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2019-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87355585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were conducted using different acrylic latex dosages with cement grouts that were prepared with water to cement ratios of 0·5, 0·4 and 0·33. The results indicated that the addition of acrylic latex of up to 5% significantly increases the 28 and 90 d strength, despite an extension of the setting time. The bleeding and resistance to acid attack of acrylic latex modified grouts were significantly improved. Grouts containing acrylic latex had much a higher viscosity and yield stress than the un-modified grouts. However, acrylic latex reduces the viscosity and yield stress of grouts that were prepared with water to cement ratios of 0·5 and 0·4 when added in small amounts. Based on the experimental results, non-linear regression analysis was performed to correlate the physical and mechanical parame...","PeriodicalId":51787,"journal":{"name":"Proceedings of the Institution of Civil Engineers-Construction Materials","volume":"46 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2019-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77551158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
