Natural Aggregates in Structural Lightweight Concrete
Pumice and scoria have been used in structural concrete since the days of the Roman Empire. Records for the past five decades show minimal use of these materials in structural concrete...

Polymer Concretes
Polymer Concrete (PC) is prepared by using polymeric materials to bond inert aggregates in a fashion similar to that of Portland Cement in the preparation of Portland Cement Concrete (PCC)....

Use of Copper Slag for Construction Purposes
Standard laboratory test results on the fine- and coarse-grained fractions of a copper slag have been presented. Based on the results of these tests, the possible use of the fine fraction...

Aggregated Water Demand Modelling in Southern California

Monksville Dam: Design Evolution and Construction
This paper documents the application of experience gained at other RCC projects to the Monskville Dam. The evolution of the design and its translation to construction are presented together...

RCC Pavements in Tasmania, Australia
Over 60,000 m**2 of high strength Roller Compacted Concrete (RCC) pavement has been completed in Tasmania, Australia, since December 1986. Projects have ranged from footpaths and small...

Roller Compacted Concrete with Marginal Aggregates
Roller compacted concrete is a technology which is vastly expanding beyond the traditional uses of pavement and dam oriented projects. Hornsby Bend Wastewater Treatment Plant required...

Influence of Lime on the Fines Content of Asphalt Concrete Mixtures

Lunar Cements/Concretes for Orbital Structures
The lunar surface is a rich source of inorganic building materials for large space structures. Lunar anorthosites can be processed into calcium aluminate cements in high temperature, high...

Segregation of Sediment During Deposition
A laboratory experiment was conducted to investigate the segregation of sediment during deposition. Sediment eroded from an upslope source area of Blount silt loam was introduced to a...

Subgrade Stabilization

Aggregation and Consolidation of Phosphatic Clays
The consolidation behavior of aggregated phosphatic clays has been investigated using a bench scale centrifuge. It was determined that aggregation of the clays with phosphogypsum, a waste...

State of the Art in Concrete-Polymer Materials
Concrete-polymer materials represent a relatively new technology in the construction industry. In some cases polymers are combined with portland cement concrete and, in other cases, polymers...

Construction of Middle Fork Dam
Recently there has been increased interest in roller compacted concrete (RCC) for use in dams. However, to date there has been very little practical experience in construction. Middle...

Uses of LP: An Aggregate Blending Example

Use of LP: An Aggregate Blending Example
The use of well known linear programs which in the past were largely confined to relatively limited mainframe usage, for the management of engineered construction is explored using a well...
