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...
Montana's Approach to Reduce Asphalt Pavement Rutting
The Montana Department of Highways experienced premature rutting in some asphalt concrete pavements primarily on the east-west interstate in Eastern Montana. Montana participated with...
Experimental Mixes to Minimize Rutting
This report describes the materials and construction details involved in the design and placement of four experimental mixes on I-95 (Richmond-Petersburg Turnpike) in 1985 and follows...
Curing Time for CRCP Mixtures Based on Flexural Strength
In this paper, the effect of different curing conditions on the flexural strength is investigated, and also the minimum required period for moist curing is found. The combined effect of...
Brittleness Index of Cementitious Composites
Series of direct tension tests were conducted to observe the softening response of different types of cementitious composites, namely, mortar, plain concrete, high strength concrete, normal...
Brittleness of High Strength Concrete
Fracture mechanics approaches are needed to determine material parameters which are related to the brittleness of concrete and its structural response. The size effect method is used to...
