Guide for the Use of Shrinkage-Compensating Concrete

Description Shrinkage-compensating concrete is made with an expansivecement or expansive component system in which initialexpansion, if properly restrained, offsets strains caused bydrying shrinkage. Since the mid-1960s, shrinkage-compensating concrete has been used in many applications. These applications include highway and airport pavements,bridge decks (Gruner and Plain 1993; Ramey et al. 1999),hydraulic structures, wastewater treatment plants, containmentstructures […]

Protection of Metals in Concrete Against Corrosion

Description The corrosion of metals, especially reinforcing steel, in concrete has received increasing attention in recent years be-cause of its widespread occurrence in certain types of structures and the high cost of repairing the structures. The corrosion of steel reinforcement was first observed in marine structures and chemical manufacturing plants.1-3 Recently, numerous reports of its

Guide for Use of Normal Weight and Heavyweight Aggregates in Concrete

Leave a Comment / Civil Books Platform, Concrete Structures Books / admin

Description Aggregates, the major constituent of concrete, influence theproperties and performance of both freshly mixed and hard-ened concrete. In addition to serving as an inexpensive filler,they impart certain positive benefits that are described in thisguide. When they perform below expectation, unsatisfactoryconcrete may result. Their important role is frequently over-looked because of their relatively low cost

Guide for Structural Lightweight-Aggregate Concrete

Leave a Comment / Civil Books Platform, Concrete Structures Books / admin

Description he objectives of this guide are to provide information and guidelines for designing and using lightweight concrete. By using such guidelines and construction practices, the struc-tures can be designed and performance predicted with the same confidence and reliability as normalweight concrete and other building materials. This guide covers the unique characteristics and perfor-mance of

Guide for Proportioning Concrete Mixtures with Ground Limestone and Other Mineral Fillers

Leave a Comment / Civil Books Platform, Concrete Structures Books / admin

Description This guide provides recommendations for proportioning normalweight concrete with ground limestone and dust-of-fracture mineral fillers. It is intended to supplement ACI 211.1. Proportioning methods for ground limestone and for dust-of-fracture mineral filler are discussed separately.Mineral filler is defined as a finely divided mineral product at least 65 percent of which passes the No. 200

Aggregate Suspension Mixture proportioning Method

Leave a Comment / Civil Books Platform, Concrete Structures Books / admin

Description This document describes the aggregate suspension mixture proportioning method. The method is suitable for normalweight concrete with workability ranging from zero-slump to self-consolidating. This method may not be suitable for mass concrete mixture proportioning. It is adapted from a method originally published by Koehler and Fowler (2007). The aggregate suspension mixture proportioning method is

Erosion of Concrete in Hydraulic Structures

Leave a Comment / Civil Books Platform, Concrete Structures Books / admin

Description Erosion is defined in this report as the progressive dis-integration of a solid by cavitation, abrasion, or chemicalaction. This report is concerned with: 1) cavitation ero-sion resulting from the collapse of vapor bubbles formedby pressure changes within a high-velocity water flow; 2)abrasion erosion of concrete in hydraulic structurescaused by water-transported silt, sand, gravel, ice,

Guide for Responsibility in Concrete Construction

Leave a Comment / Civil Books Platform, Concrete Structures Books / admin

Description The responsibilities of each party in a concrete construc-tion project, including the responsibility for the owner’s project objectives such as (in no particular order) schedule, functionality, and sustainability, should be adequately described in the contracts between the parties. It is important that the party controlling that process (usually the owner or an owner’s representative)

Information Delivery Manual (IDM) for Cast-in-Place Concrete

Leave a Comment / Civil Books Platform, Concrete Structures Books / admin

Description An information delivery manual (IDM) defines exchange requirements in the context of reference industry processes. IDMs are defined by end users and practicing professionals to support the process in which they are expert. The resulting IDM serves to define the exchange requirements for one or more building information modeling (BIM) transactions. The IDM is
