In the present work, effect of inclusion silica fume on performance natural pozzolan-based cement concrete was investigated. Natural pozzolan, obtained from volcanic rocks, used as main supplementary cementitious material to partially replace Portland cement. Silica admixed at an optimum dosage, optimally selected based several trial mixtures, in attempt improve concrete. Compressive strength, drying shrinkage, water penetration depth, coefficient chloride diffusion, carbonation...

This paper presents a study on the shear behavior of reinforced concrete (RC) beams strengthened by jacketing surfaces using ultra-high performance fiber (UHPC). The RC were prepared sandblasting and UHPC was cast in situ over beams. two different strengthening configurations; (i) longitudinal sides (ii) three strengthening. bond between normal examined conducting splitting tensile strength slant tests composite cylindrical specimens UHPC. control beam tested four-point loading arrangement...
The analytical prediction of residual flexural strength corroded beams has been revisited in the context relatively larger size reinforced with diameter tension bars to exclude size-effect proposed modelling and improve further accuracy method. Most past research, including that conducted by authors, used smaller beam specimens generate test data for modelling. A new experimental programme was undertaken using 48 width 200 mm depth varying from 215 315 mm, 16 18 diameter. were subjected a...
In the exploratory study presented in this paper, an attempt was made to develop different mixtures of ultrahigh performance concrete (UHPC) using various locally available natural and industrial waste materials as partial replacements silica fume sand. Materials such pozzolana (NP), fly ash (FA), limestone powder (LSP), cement kiln dust (CKD), pulverized steel slag (PSS), all which are abundantly Saudi Arabia at little or no cost, were employed development UHPC mixtures. A base mixture...
This computational investigation focused on numerical modeling of the shear behavior ultra‐high‐performance concrete (UHPC) beams reinforced longitudinally with high‐strength rebars and ordinary‐strength steel (stirrups). Nonlinear three‐dimensional finite element model, using damaged plasticity model material properties obtained from uniaxial compressive tensile laboratory tests, was conducted to simulate UHPC within a commercial software package ABAQUS 6.13. included effects various...
Existence of ultra-high performance concrete (UHPC) is the result one latest advances in technology. As compared to normal mixtures, mixtures UHPC are reported have several times more strength, elastic modulus, fracture toughness, ductility and durability. prepared by mixing high amounts cement silica fume with fine quartz sand, powder fibres. The water binder ratio kept very low therefore a dosage superplasticizer needed maintain required flowability. Need for sand producing increases cost...
