Effect of different burning degrees of sugarcane leaf ash on the properties of ultrahigh-strength concrete
TL;DR: In this article , the authors investigated the effect of using sugarcane leaf ash (SLA) as a pozzolanic material on the properties of UHSC and showed the efficiency of using SLA as a partial substitute of the 20% of cement weight with mechanical properties and durability higher than the mechanical properties of the reference mixture.

Effect of aggregate and fibre types on ultra-high-performance concrete designed for radiation shielding
TL;DR: In this paper , the authors examined the properties of ultra-high performance (UHPC) and heavyweight radiation shielding concrete, and several types of heavy-weight fine aggregates (sand, magnetite, hematite ilmenite and barite) were used to achieve these properties.

TL;DR: In this article, the authors present the following properties of concrete: Elasticity, Shrinkage and Creep, Durabilty of Concrete, Freezing and Thawing, and Chlorides.
Journal ArticleDOI
Effects of elevated temperatures on properties of concrete
TL;DR: In this article, the effects of elevated temperatures on the physical and mechanical properties of various concrete mixtures prepared by ordinary Portland cement, crushed limestone, and river gravel were investigated and the results indicated that the relative strength of concrete decreased as the exposure temperature increased.
Journal ArticleDOI
Water-entrained cement-based materials: II. Experimental observations
TL;DR: In this paper, a new concept for the prevention of self-desiccation in hardening cement-based materials is proposed based on using fine, superabsorbent polymer (hydrogel, SAP) particles as a concrete admixture.
Journal ArticleDOI
Mechanical properties of concrete at high temperature—A review
TL;DR: In this paper, the authors provide a comprehensive and updated report on the temperature dependency of such parameters as the compressive strength, modulus of elasticity, strength in indirect tension (bending and splitting tests), stress-strain curves and spalling, but the roles played by the water-binder ratio (w/b), aggregate type, supplementary cementitious materials (SCMs) and fibres are investigated as well.

Prevention of autogenous shrinkage in high-strength concrete by internal curing using wet lightweight aggregates
TL;DR: In this paper, a partial replacement of normal-weight aggregate by saturated lightweight aggregate was shown to be effective in eliminating the autogenous shrinkage and restrained stresses of the normal weight concrete.
