Abstract: In cold regions, early deterioration of concretes due to freezing and thawing is a major concern. This study determined the freezing and thawing resistance of ultrahigh-performance concretes (UHPCs) made with different ...

Abstract: The sulfate resistance of concrete pavers was determined using a method based on ASTM C 1012. Specimens were submerged in a 5% sodium sulfate solution for a period of one year. Length change and loss in mass were determined. ...

Abstract: This paper presents experimental results regarding freezing and thawing performance of various concrete paving blocks using a standard accelerated laboratory test, ASTM C 666, procedure A. A total of 124 paving blocks ...

Abstract: In the production of self-consolidating concrete (SCC), long hauling times are often necessary for transportation to the job site. During such hauling time, highly fluid SCC can lose a significant amount of slump flow, ...

Abstract: This investigation studied the retempering technique of remediation to mitigate the influence of combined transportation time and extreme hot and cold temperatures on plastic self-consolidating concrete (SCC). This method ...

Abstract: In this study the physical and engineering characteristics of various no-fines concrete mixtures are investigated. No-fines concrete mixtures subjected to impact compaction are studied under unconfined compression, indirect ...

Abstract: No-fines concrete is defined as a type of concrete from which the fine aggregate component of the matrix is entirely omitted. The aggregate is of a single size and the finished product is a cellular concrete of comparatively ...

Abstract: A pilot study was undertaken on the use of lignite-based bottom ash as a fine aggregate in structural grade concrete. Bottom ash is combined with portland cement, crushed limestone coarse aggregate, and water to produce ...

Abstract: The investigation presented herein was intended to study the influence of combined transportation time and hot and cold temperatures on the flow properties of self-consolidating concretes (SCC). Seven different temperatures ...

Abstract: No-fines concrete is a type of concrete from which the fine aggregate is totally omitted and single-sized coarse aggregates are held together by a binder consisting of a paste of hydraulic cement and water. The earliest ...
