Research Report ICAR 101-1
An Investigation of the Status of By-Product Fines in the United States

The handling and disposal of fines produced as a result of the aggregate crushing and production process are some of the major problems facing the aggregate industry today, having both economic and environmental implications. This report describes a major effort undertaken to quantify and characterize these fines, their location, character, and sales.

Research Report ICAR 101-2F
Framework for Development of a Classification Procedure for Use of Aggregate Fines in Concrete

The focus of this project was to examine the methods and test procedures used in the past to characterize the properties of fines, and develop, on a preliminary basis, a framework to characterize and catalogue the properties of aggregate fines, propose new ones that would eventually complement a set of guidelines for the use of aggregate fines in portland cement concrete. Possible applications of aggregate fines, such as in high-performance concrete, controlled low strength materials, and insulated concrete forms are discussed as future directions of research.

Research Report ICAR 102-1F
An Experimental Study on the Guidelines for Using Higher Contents of Aggregate Microfines in Portland Cement Concrete

This report presents some of the effects of high fines on the properties of cement mortar and concrete.

ICAR 103: Use of High Fines Concrete (HFC) in Insulated Concrete Form (ICF) Construction
This project work consisted of developing technical data to justify, from the standpoint of material properties (of aggregate fines and HFC), construction efficiency, cost competitiveness, and energy performance, a basis for the use of high-fines concrete (HFC) inside ICF wall systems.

ICAR 104: Guidelines for Proportioning Optimized Concrete Mixtures with High Microfines
The optimization of aggregates is advantageous for economical and technical reasons; however, the availability of materials and construction operations can dictate the proportions of fine and coarse aggregates. Some general guidelines based on field experience, other investigations and the results of this investigation are presented.

ICAR 104-1F: The Effects of Aggregates Characteristics on the Performance of Portland Cement Concrete
The effect of shape, texture and grading of aggregates on fresh concrete was evaluated experimentally, quantified by means a proportioning method based on packing density concepts, the Compressible Packing Model (CPM), and analyzed by an empirical tool suggested by Shilstone.

ICAR 105-1: Summary of Concrete Workability Test Methods
This project describes 61 test methods for measuring concrete workability.

ICAR 105-2: Qualification of Concrete Workability by Means of the Vibrating Slope Apparatus
A new device, the Vibrating Slope Apparatus (VSA), developed for qualifying concrete workability under vibration, was borrowed by the International Center for Aggregates Research (ICAR) Project 105 researchers for evaluation.

ICAR 105-3F: Development of a Portable Rheometer for Fresh Portland Cement Concrete
The purpose of this research was to identify an effective field test method for measuring the workability of concrete in general and of high-microfines concrete in particular.

ICAR 201 Series: Superpave Aggregate Specifications
A comprehensive research program was conducted in three concurrent phases which examined the Superpave fine aggregate angularity (FAA) test, the restricted zone requirement, and the voids in the mineral (VMA) specification.

Research Report ICAR 301-1F
Alkali-Silica Reaction in Portland Cement Concrete: Testing Methods and Mitigation Alternatives, (pp 548)

Identifying the susceptibility of an aggregate to alkali-silica reaction (ASR) before using it in concrete is one of the most efficient practices for preventing damage and failure.

ICAR 501 Series: Increased Single-Lift Thicknesses for Aggregate Base Courses
This project was initiated specifically to investigate the potential for placing unbound aggregate base courses in thicker lifts to improve pavement performance, reduce costs, and increase the amount of aggregates used.

In this 501 series you will find the following reports:
