b) Discuss ... -
ACI 216.1
Abstract: This standard describes acceptable methods for determining the fire resistance of concrete and masonry building assemblies and structural elements, including walls, floor and roof slabs, beams, columns, lintels, and masonry ... -
ACI 423.9M
Abstract: This test method is designed to determine the resistance to bleeding of freshly-mixed cementitious grout under static pressure.
The values stated in SI units are to be regarded as standard. No other units of measurement ...Subject(s) : bleed stability , bleed water , bleeding , grout , posttensioning , pressure , -
ACI 325.13R
Abstract: This guide covers the design of jointed plain concrete pavements (JPCP) for use on city streets and local roads (driveways, alleyways, and residential roads) that carry low volumes of traffic. This document is intended to ... -

Abstract: The purpose of this guide is to give the reader a working knowledge of emulation and emulative detailing to meet requirements in current codes. The term "emulation" has become a common concept for designers working with ...Subject(s) : ductility , elastic design , emulation , flexural strength , joint , precast concrete , precast detailing , reinforcement , -
ACI 549R
Abstract: INTRODUCTION: The construction of ferrocement can be divided into four phases:
1. fabricating the steel rods to form a skeletal framing system;
2. tying or fastening rods and mesh to the skeletal framing;
3. ... -
ACI 349.1R
Abstract: INTRODUCTION
ACI 349, Appendix A, provides general considerations in designing reinforced concrete structures for nuclear power plants. The Commentary to Appendix A, Section A.3.3, addresses three ... -
ACI 544.1R
Abstract: INTRODUCTION
Historical aspects
Since ancient times, fibers have been used to reinforce brittle materials. Straw was used to reinforce sun-baked bricks, and horsehair was used to ... -
