Torsional Strengthening Of Normal Weight Concrete And Light Weight Concrete Using Steel Fibres
Materials Today: Proceedings, 2017Abstract Forces that twist a member about a longitudinal axis are called torsional loads. Modern day structures using conventional concrete which are tall and aesthetically pleasing is in need of torsional strengthening. In this study, torsional behaviour of normal weight concrete (NWC) and light weight concrete (LWC) is analysed.

Experimental investigation on steel-concrete bond in lightweight and normal weight concrete
Structural Engineering and Mechanics, 2004The bonding behaviors of Lightweight Aggregate Concrete (LWAC) and normal weight concrete were investigated experimentally. Pull-out tests were carried out to measure the bond strengths of three groups of specimens with compressive strength levels of 60, 40, and 20 MPa, respectively.

Highly absorptive normal weight aggregates for internal curing of concrete
Construction and Building Materials, 2018Abstract The objective of this research was to develop an internal curing (IC) approach aiming to reduce early-age shrinkage and maintain the materials properties intact. Attention was given on delivering curing water within the material’s structure using existing constituents of the mixture.

Construction and Building Materials, 2008
This paper presents a study on accelerated carbonation testing of normal weight concrete (NWC) and lightweight concrete (LWC) mixes proportioned for three levels of strength grades. Two types of curing regimes were applied; (1) hot curing in water at 60 C for 3 days and (2) normal curing in water at 27 C for 28 days.

Experimental and Numerical Characterization of Normal-Weight Concrete at the Mesoscale
Journal of Materials in Civil Engineering, 2022Modeling the postpeak behavior of brittle materials like concrete remains a challenge from the point of view of computational mechanics due to the strong nonlinearities arising in the material behavior during softening and the complexity of the yield criterion that may describe their deformation capacity under generic triaxial stress states.

STUDY OF SHRINKAGE OF CONCRETE USING NORMAL WEIGHT AND LIGHTWEIGHT AGGREGATE
International Journal of Engineering Applied Sciences and Technology, 2021Drying shrinkage can be a major cause of deterioration of concrete structures. Aggregate sizes, curing period and water-cement ratio imparts a great impact on shrinkage of concrete. This paper represents the observed effects of water-cement ratio, curing period and aggregate sizes on shrinkage of concrete using normal weight and lightweight aggregate ...

On Static Modulus of Elasticity of Normal‐Weight Concrete
Journal of Structural Engineering, 1989The modulus of elasticity of concrete is a fundamental parameter in analysis and design of reinforced‐concrete structures. The present ACI approach for Young's modulus is based on normal strength concrete. It may not be appropriate for high‐strength concrete.
