This book was released on 1998 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this research is to evaluate how transport properties at the surface and in the core of high-performance concrete (HPC) slabs are affected by silica fume and by superplasticizer and retarding agent dosages. The transport properties were evaluated by measuring the air permeability at two depths under the surface finished with a wooden trowel. The experimental program is based on eight different high-performance concrete mixtures (77 to 93 MPa) made with a water-to-binder ratio of 0.30. An ordinary portland cement (OPC) and a blended silica-fume cement (SF) were used to compare the effect of silica fume on the air permeability of surface and core concrete. Four mixtures were produced with a retarding agent to assess the effect of set retardation on the surface properties of high-performance concrete. For each combination of cement type and retarding agent dosages, the superplasticizer dosage was selected to produce two slump levels of 100 ± 10 mm and 200 ± 20 mm.

This book was released on 2012-01-02 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the state-of-the-art report prepared by the RILEM TC “Application of Super Absorbent Polymers (SAP) in concrete construction”. It gives a comprehensive overview of the properties of SAP, specific water absorption and desorption behaviour of SAP in fresh and hardening concrete, effects of the SAP addition on rheological properties of fresh concrete, changes of cement paste microstructure and mechanical properties of concrete. Furthermore, the key advantages of using SAP are described in detail: the ability of this material to act as an internal curing agent to mitigate autogenous shrinkage of high-performance concrete, the possibility to use SAP as an alternative to air-entrainment agents in order to increase the frost resistance of concrete, and finally, the benefit of steering the rheology of fresh cement-based materials. The final chapter describes the first existing and numerous prospective applications for this new concrete additive.

This book was released on 1997 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been prepared with the aim of integrating information about the chemistry and application of concrete superplasticizers in a manner relevant to concrete engineers and technologists. The opening chapter introduces basic aspects of concrete science as background for what follows. Chapters 2-4 discuss the chemical synthesis of superplasticizers, methods used to characterize those chemicals, and techniques for evaluation of their effect in cementitious systems. Subsequent chapters cover: the influence of superplasticizers on hydration of cement materials; rheology of cementitious systems; issues related to the mode of action and compatibility of superplasticizers; the effect of superplasticizers on fresh concrete; mechanical properties and durability of concrete; innovative applications of superplasticizers in concrete; superplasticizer dispensing, specifications, and standards; patents related to superplasticizers; and current and future trends in the use of superplasticizers in concrete.

Download or read book Mechanical Properties and Freezing and Thawing Resistance of High Strength Concrete Incorporating Silica Fume written by VM. Malhotra and published by . This book was released on 1987 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents results of an investigation dealing with the mechanical properties and freezing and thawing resistance of high-strength, silica fume concrete using ASTM Test Method for Resistance of Concrete to Rapid Freezing and Thawing (C 666-84, Procedure A). Eighteen nonair-entrained and six air-entrained concrete mixtures, 0.06 m3 in size, were made. The water-to-(cement + silica fume) ratio (W/C + S) of the mixtures ranged from 0.25 to 0.36, and the percentages of cement replacement by silica fume were 0, 10, and 20% on a weight basis. Any loss in slump due to the use of silica fume was compensated for by the use of a superplasticizer.
