Effect of Temperature on Pore Structure and Strength of Concrete
Abstract The aim of this study is to quantitatively determine the effect of elevated temperatures on the pore structure and compressive strength of concrete. To minimize the effect of the hydration process, thermal and endogenous shrinkage, concrete cured in water for...
Effect of Particle Size Distribution of Sand on Mechanical Properties of Cement Mortar
Abstract Despite the many research studies on the effect of the particle size distribution (PSD) of sand and microsilica content on the mechanical properties of cement mortar, there has not been a comprehensive study investigating the effect of the PSD curve...
Portland Cement Concrete Deformation Modulus: Influence of Paste Volume
Abstract The dimensioning of structural systems in reinforced or prestressed concrete requires knowledge, among other properties, at least of the deformation modulus and compressive strength. However, concrete may present enough strength, whereas the structure...
Discussion on Problem of Standard Deviation of Concrete Strength
Abstract This paper discusses the characteristics of the standard deviation of concrete specimen strength and the relationship between the standard deviation of concrete strength and the average value of strength. It is revealed that strength standard deviation of a...
Splitting Tensile Strength of Concrete Corroded by Saline Soil
Abstract This paper reports the splitting tensile strength of concrete corroded by saline soil. The wet-dry cycle erosion test and splitting tensile test were performed on concrete cubic specimens with six different erosion inspection periods and a solution with the...
Continuously Reinforced Concrete Pavement under Temperature Loading
Abstract Continuously reinforced concrete pavement (CRCP) has superior durability and mechanical performance over jointed plain concrete pavement (JPCP) without preset joints. However, there are many small cracks in CRCP under environmental loading. Crack width of...
Development of G-GBFSD Geopolymer Concrete
Abstract Development of geopolymer concrete (GPC) with industrial by-products is a solution to the disposal of the industrial wastes, thus making the concreting process sustainable. This paper focuses on the development of GPC using ground-granulated blast-furnace...
Effect of Coatings on Concrete Resistance to Physical Salt Attac
Abstract In this study, different types of surface coatings were applied to concrete to assess their suitability for resisting physical salt attack (PSA). Concretes with different water-binder ratios (w/b) were tested and severe PSA conditions were implemented, using...
Evaluating Curling Stress of Continuous Reinforced Concrete Pavement
Abstract A realistic assessment of the effect of curling stress on long-term performance of continuous reinforced concrete pavement (CRCP) is required in rational design. The main objective of this research is to quantify the thermal behavior of CRCP and the curling...
