This book was released on 1984 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of no-slump, roller-compacted concrete (RCC) in mass concrete construction was investigated. RCC is concrete having no slump but containing the minimum amount of water necessary to achieve consolidation with a vibrating roller. Tests were conducted to: (a) optimize mixtures for application of no-slump techniques, (b) develop a consistency and quality control technique, (c) determine methods of improving hardened lifts joints, (d) determine the relative frost resistance of RCC, (e) evaluate the erosion susceptibility, and (f) discover economical methods of obtaining void-free vertical surfaces. Indications are that: (a) the curb concrete is viable method of forming and containing RCC; (b) the degree of compaction achieved is dependent on the stiffness and the paste content of the mixture, the lift thickness, and the individual roller; (c) the tensile strength of the untreated joints increased with paste content and quality from approximately 25 percent for relatively lean RCC to approximately 50 percent for richer RCC; (d) erosion resistance at 35-ft/sec fluid velocity of RCC is good; (e) resistance to freezing and thawing of the RCC is poor, apparently due to a poor air void system; and (f) surface treatment with a mortar gun (shotcrete) appears to be a practical method to achieve smooth vertical surfaces.

Book excerpt: Roller compacted concrete (RCC) is discussed in this special technical publication for the first time. The widespread use of RCC has occurred in the period since publication of the last version of ASTM STP 169B in 1978. Initial development, in the 1970s, was focused primarily on mass concrete for construction of locks and dams. In the 1980s, RCC was adapted for use in construction of pavements and other types of horizontal structures. Recently, in the 1990s, it has been applied as a repair technique to several types of structures.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a laboratory investigation that was conducted for the purpose of validating mixer- uniformity requirements for roller-compacted concrete. The purpose of the investigation was to verify existing guidance or, if necessary, recommend changes to existing guidance. The investigation included both air-entrained and nonair-entrained concrete. The results indicate that existing guidance is appropriate for Vebe consistency, water content, coarse aggregate content, compressive strength, and air-content determinations. However, the results indicated that existing guidance could he too restrictive for the unit weight of air-free mortar determinations. A recommendation was made to consider revising current guidance on the allowable range for unit weight of air-free mortar.

Available in PDF, EPUB and Kindle. Book excerpt: Roller-compacted concrete (rcc) pavement is a mixture of open graded aggregate portland cement and water which is blended into a homogeneous mass with the consistency of zero-slump concrete and the appearance of damp gravel. this paper describes recent investigations to develop the engineering properties of rcc and presents a procedure for the thickness design of rcc pavements. the procedure requires computation of the allowable pavement stress based on the number of total load applications and computation of the expected pavement stress due to the design wheel loading. the paper also describes changes and improvements in the placing and compaction of rcc pavements to produce the desired physical and performance properties of the pavement. for the covering abstract of the conference see irrd 807058.

Download or read book Dynamic Mechanical Behaviors and Constitutive Model of Roller Compacted Concrete written by Sherong Zhang and published by Springer Nature. This book was released on 2023-03-01 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book systematically illustrates the dynamic mechanical behaviors and discusses the fundamentals of the constitutive modeling of roller-compacted concrete (RCC), influenced by the construction technique and mix design. Four typical problems are analyzed using laboratory tests, numerical simulation and theoretical analysis, i.e., to illustrate the special dynamic mechanical behaviors of RCC, to reveal the dynamic size-dependence of mechanical properties, to discuss the aggregate size effect on dynamic mechanical properties, and to modify the dynamic constitutive model for RCC. Generally, the constitutive modeling of RCC needs a comprehensive understanding of dynamic size-dependence and aggregate size effect of concrete that coupled with the strain-rate sensitivity. So that, readers can master the modified dynamic constitutive model of RCC to analyze and solve the problems in blast-resistance analysis and protective design of RCC dams. This book can be used as a postgraduate textbook for civil and hydraulic engineering in colleges and universities, and as an elective course for senior undergraduates. It can also be used as a reference for relevant professional scientific researchers and engineers in field of protective design of concrete structures.
