Optimizing of Steel Fiber Reinforced Concrete Mix Design
Cementitious matrices are the fragile materials that possess a low tensile strength. The addition of fibers randomly distributed in these matrices improves their resistance to cracking, substantially. However, the incorporation of fibers into a plain concrete disrupts the granular skeleton and quickly causes problems of mixing as a result of the loss of mixture workability that will be translat...
متن کاملProperties of Green Lightweight Aggregate Concrete
With increasing concern over the excessive exploitation of natural aggregates, synthetic lightweight aggregate produced from environmental waste is a viable new source of structural aggregate material. The uses of structural grade lightweight concrete reduce considerably the self-load of a structure and permit larger precast units to be handled. In this paper, the mechanical properties of a str...
متن کاملFEM models of composite timber-lightweight concrete floor systems
Paper presents the main principals in designing wood-lightweight concrete composite floor structures using FEM models. All design-related analyses are performed by means of the FEA COSMOS/M program. Paper emphasises some important details in FEM model design (how to choose appropriate finite elements for different types of materials, how to connect concrete slab and timber beams to work togethe...
متن کاملinternal curing of high strength self consolidating concrete by saturated lightweight aggregate - effects on material properties
self-desiccation is the major source of autogenous shrinkage and crack formation in low water-binder ratio (w/b) concretes which can be reduced by internal curing. in this paper performance of high strength self consolidating concrete (hs-scc) with w/b of 0.28 and 0.33 including autogenous shrinkage, drying shrinkage, compressive strength, and resistance to freezing-thawing was investigated. th...
متن کاملOptimization of concrete mix proportioning
The aim of this paper is to carried out statistical analysis for optimization of various concrete mix proportions by using full factorial experimental technique. The variables such as 28 days cube compressive strength, water to cement ratio (w/c), coarse aggregate to total aggregate ratio (CA/TA) and total aggregate to cement ratio (TA/C) were the parameters to be used for optimization. Four w/...
