ABSTRACT Blast-furnace slag (BFS) cement has been often used for civil engineering structures, but it has rarely been used for reinforced concrete buildings because of slow strength development. The purpose [...]

ABSTRACT This document comprehensively studies the quantitative kinetics of pozzolanic reactions of class C and F and cofired biomass fly ashes with Ca[(OH).sub.2] (CH) under carbonation free conditions. The grams [...]

ABSTRACT Silica-breccia (SB), also known as Aplite, is a newly discovered supplementary cementing material (SCM) that has shown to have some pozzolanic effect when mixed with cement. Like any other [...]

ABSTRACT This paper presents the effect ultrafine fly ash (UFFA) on compressive strength development of mortars containing high volume class F fly ash as partial replacement of cement. The experimental [...]

ABSTRACT In this study, the use of lightweight aggregate (LWA) for making lightweight pervious concrete (LWPC) was presented. Diatomite (DA) and pumice (PA) were used as natural LWAs in pervious [...]

ABSTRACT Pervious concrete has been increasingly used to reduce the amount of runoff water and improve the water quality near pavements and parking lots. However, due to the significantly reduced [...]

ABSTRACT Recycled concrete aggregates mainly differ from natural aggregates in that they are composed of two different materials: natural aggregate and cement mortar attached. It is well known that cement [...]

ABSTRACT Ninety pullout specimens were used to study the bond behavior of glass fiber reinforced polymer (GFRP) ribbed rebars with thirty different specially designed rib geometries to the normal strength [...]

Abstract In this paper, a finite point method (FPM) is developed and adopted for solving the chloride diffusion equation for prediction of service life of concrete structures and initiation time [...]

Abstract In this study, cement has been replaced with a Class C fly ash (FA) in various proportions from 30% to 60%. Durability properties of various self-compacting concrete (SCC) mixtures [...]

Abstract This paper describes a series of experiments in characterizing the pore systems of mature and hardened air-cured and water-cured concrete specimens. The characterization was achieved by measuring the real [...]

Abstract The research described herein was conducted as a part of NCHRP Project 18-04B, Early Opening-to-Traffic Portland Cement Concrete for Pavement Rehabilitation [Van Dam TJ. Durability of 'Early-Opening-to-Traffic' portland cement [...]

Abstract It is an undeniable fact that concrete is the most widely used man-made construction material in the world today, and will remain so for decades to come. The popularity [...]

Pigs don't fly, concrete doesn't float, and miracles don't happen--only one of these statements remained true when engineering schools from across North America gathered last June in Montreal for the [...]
