prediction compressive strength of concretes containing silica fume and styrene-butadiene rubber (sbr) with a mathematical model

چکیده
this paper deals with the interfacial effects of silica fume (sf) and styrene-butadiene polymer (sbr) on compressive strength of concrete. analyzing the compressive strength results of 32 concrete mixes performed over two water-binder ratios (0.35, 0.45), four percentages replacement of silica fume (0%, 5%, 7.5%, 10%) and four percentages of sbr (0%, 5%, 10%, 15%) were investigated. a mathematical model base on abrams’ law has been proposed for evaluation strength of silica fume-sbr concretes. this simplified model might serve as useful guides for commixture concrete admixtures containing of silica fume and sbr. the accuracy of the proposed model is investigated

service life prediction of silica fume concretes
deterioration of concrete structures in the gulf region is a serious problem. penetration of chloride ion into concrete is responsible for such early deterioration. determination of chloride diffusion coefficient is an effective way to predict the service life of concrete structures. in order to investigate the performance of concrete mixtures in such environments, ordinary and silica fume conc...

Ceramifiable styrene-butadiene (SBR)-based composites containing low-softening-point-temperature glassy frit promoting ceramification, precipitated silica, one of four thermally stable refractory fillers (halloysite, calcined kaolin, mica or wollastonite) and a sulfur-based curing system were prepared. Kinetics of vulcanization and basic mechanical properties were analyzed and added as Suppleme...
متن کاملThe Effect of Styrene-Butadiene-Rubber (SBR) Polymer Modifier on Properties of Bitumen
Abstract—In order to use bitumen in hot mix asphalt, it must have specific characteristics. There are some methods to reach these properties. Using polymer modifiers are one of the methods to modify the bitumen properties. In this paper the effect of StyreneButadiene-Rubber that is one of the bitumen polymer modifiers on rheology properties of bitumen is studied. In this regard, the rheological...
متن کاملAn Investigation on In-situ Strength and Bonding Strength of Polymer Modified Concretes (PMC) as Repair Overlays on Conventional Concrete Substrate
Polymer modified concrete (PMC) consists of Portland cement concrete with a polymer modifier. Its advantages are proper bonding strength to substrate concrete, high tensile and flexural strength and low amount of shrinkage and permeability. Using PMC overlays can be considered as a method for preservation of damaged concrete structures due to their suitable performance and durability. In this r...
