Durability of Fly Ash Concrete in the Marine Environment
This paper presents the experimental investigation of durability of air-entrained fly ash concrete in the marine environment. The findings indicate that the deterioration rate of durability...
Effect of Fly Ash on the Microstructure and Durability of Concrete
The influence of fly ash on the microstructure and durability of concrete was investigated. It was found that the use of 50% fly ash in concrete reduced greatly its resistance to freezing-and-thawing...
Permeability Effects on the Sulfate Resistance of Concrete
A laboratory study was conducted to determine the effect of permeability on the sulfate resistance of concrete containing fly ash. Concrete specimens were moist cured for 7 and 100 days...
High Performance Fiber Reinforced Cement-Based Composites
Fracture of cement-based composites reinforced by the relative high fiber volume is studied. Crack propagation and damage distribution were examined by laser holographic interferometry....
Material Properties Related to Pavement Performance
As part of the Strategic Highway Research Program, an effort has been made to review research literature which can be used to relate asphalt properties to pavement performance. This report...
Relationship Between Laboratory Aging Tests and Field Performance of Asphalt-Concrete Mixtures
Aging of asphalt mixtures is primarily associated with loss of volatile components and oxidation in asphalt during the construction phase (short-term aging), and progressive oxidation...
Innovative Uses of Polymer Concrete
Polymer concrete (PC) was developed in the 1950s. The material became more widely known in the 1970s when it was used for the repair of portland cement concrete. Polymer concrete is significantly...
Properties of a New Polymer Concrete
A new polymer concrete was developed by adding unsaturated polyester resin and emulsifier into concrete. The new polymer concrete exhibits high strength of up to 69 MPa (10,000 psi) for...
Aggregates, Fibers and Coupling Agent in Polyester PC
This study investigated the influence of fine aggregate, glass fiber and silane coupling agent on the mechanical and mode I fracture behavior of a polyester polymer concrete (PC). The...
Beam-To-Column Connections for Pultruded FRP Structures
Moment-rotation and strength characteristics of beam-to-column bolted connections of fiber reinforced plastic (FRP) pultruded wide-flange structural shapes are discussed. Results of experimental...
Time-Dependent Behavior of FRP Lintels
This paper describes an experimental investigation into the short-term and long-term behaviors of two types of T-shaped lintels made of fiber-glass reinforced plastic with polyester or...
Load-Deflection Performance of FRP Molded Grating
This research project deals with fiberglass reinforced plastic (FRP) molded grating, its properties, manufacturing materials used and appearance. Grating strength, configuration, weight...
Shear Properties of Pultruded Glass FRP Materials
The in-plane shear modulus and the in-plane shear strength of a variety of pultruded glass fiber reinforced plastic (FRP) materials were measured experimentally in a pilot test program...
Early-Time Strength and Elastic Modulus of Concrete With High Proportions of Fly Ash
Compressive strength and elastic modulus data are presented for four concrete mixtures with ratios (by volume) of Class C fly ash to total cementitious materials (portland cement plus...
Strength, Durability and Creep of Fly-Ash Concrete: Part I
In this paper, strength of concretes and mortars containing various proportions of fly ash were examined. For strength tests four types of Canadian and one type of American ash were used...
Strength, Durability and Creep of Fly-Ash Concrete: Part II
Tests on sulphate durability of various plain and fly ash mortars soaked in pH-controlled sulphate solutions were performed. The performance of several types of ash have been examined,...
70 Year Performance Record for High Strength Structural Lightweight Concrete
The paper briefly discusses the first ship built using expanded aggregates manufactured in a rotary kiln the USS Selma. It then goes on to discuss achieving high strength concrete with...
High Strength, High Denier Discrete Polymer Fiber in Cementitious Composites
A series of 3-point beam tests were performed on the cementitious composites specimens reinforced with high strength, high denier discrete polyester fibers. The fiber length, fiber volume...
Field Performance of Fiber Reinforced Concrete Highway Pavements
This paper reports the evaluation of field performance of fiber reinforced concrete pavements. The concrete was designed for a compressive strength of about 40 MPa. Steel fibers with hooked...
