Foreword to Significance of Tests and Properties of Concrete
THIS PUBLICATION is a revision and enlargement of Significance of Tests and Properties of Concrete and Concrete-Making Materials (STP 169C) revealed in 1994.
That publication in flip changed editions revealed in 1956, 1966, and 1978.
The current publication features a quantity of new supplies and check strategies which were developed, or supplies which have elevated in significance because the 1994 version.
Two most helpful additions are the chapters on slag as a cementitious materials and self-consolidating concrete.
As within the earlier editions, chapters have been authored by people chosen on the idea of their information of their topic areas,
and most often as a result of of their participation within the growth of pertinent specs and check strategies by ASTM Committee C09 on Concrete and Concrete Aggregates and, in some circumstances, ASTM Committee C01 on Cement.
The authors developed their chapters in conformance with normal tips solely. Every chapter has been reviewed and, the place essential, coordinated with chapters by which overlap of subject material may happen.
This newest version has been developed underneath the course of the Govt Committee of ASTM Committee C09 by coeditors Joseph F. Lamond, Consulting Engineer, and James H. Pielert, Advisor, each members of Committee C09.
Introduction to Significance of Tests and Properties of Concrete
ASTM STP 169C, SIGNIFICANCE OF TESTS AND Properties of Concrete and Concrete-Making Materials, was revealed in 1994.
ASTM Committee C9 on Concrete and Concrete Aggregates has as soon as once more determined the time was acceptable to replace and revise this handy publication to replicate adjustments within the expertise of concrete and concrete-making supplies which have taken place since that point.
New supplies have appeared on the scene, together with a larger appreciation of the capabilities of concrete as a fundamental building materials.
Committee C9 and its subcommittees have made important adjustments in lots of of its specs and check strategies to replicate these adjustments.
New specs and testing strategies have been developed to supply for knowledgeable use of new supplies and new makes use of for concrete.
Hydraulic cement concrete is a product composed of many supplies and produced in lots of kinds.
The standard of concrete depends on the standard of the constituent supplies and associated manufacturing, testing, and set up processes.
Since 1914, ASTM Committee C9 has performed a significant function in selling the standard of concrete by growing specs, testing strategies, and practices for concrete and concrete-making supplies.
This has been doable by means of the dedication and dedication of its volunteer members through the years. Committee C9 first revealed Report on Significance of Tests of Concrete and Concrete Aggregates, ASTM STP 22, in 1935, with an up to date report revealed in 1943.
ASTM STP 169 was revealed in 1956, adopted by ASTM STP 169A in 1966, ASTM STP 169B in 1978, and ASTM STP 169C in 1994.
Following this temporary introduction, this particular publication is organized into six components: Normal, Freshly Combined Concrete,
Hardened Concrete, Concrete Aggregates, Concrete-Making Materials Aside from Aggregates, and Specialised Concretes, with revised and new chapters.
In Half I, the chapters consist of normal topics on the character of concrete, sampling, variability, and testing laboratories. A brand new chapter offers with modeling cement and concrete properties.
Half II offers with the properties of freshly combined concrete.
Half III issues itself with the properties of hardened concrete.
Half IV offers with concrete aggregates.
The order of the chapters has been revised. They’re now offered within the order that the majority issues concrete customers: grading, density, soundness, degradation resistance, petrographic examination, reactivity, and thermal properties.
Some of the chapter titles have modified and the earlier chapter on pore programs has been included within the chapter on density.
Half V consists of supplies aside from aggregates. The title of the chapter on curing supplies was modified to replicate present expertise of supplies utilized to new concrete surfaces.
The chapter on mineral admixtures has been separated into two chapters, one on supplementary cementitious supplies and the opposite on floor slag.
Half VI, on specialised concretes, incorporates one new chapter on self-consolidating concrete.
The subcommittee construction of Committee C9 has been modified to accommodate this want.
The editors, together with ASTM Committee C9 on Concrete and Concrete Aggregates, imagine this new version will serve the concrete trade properly.
The editors chosen authors and their chapters have been reviewed in accordance with ASTM’s peer evaluation procedures.
C9 subcommittees having jurisdiction over the topics for pertinent chapters participated informally within the evaluation course of.
The editors recognize the assistance and steering of these folks and the cooperation of ASTM Committee C1 on Cement in offering authors for the 2 chapters on cement.
Some of the authors in ASTM 169C are now not energetic in Committee C9.
The co-editors and Committee C9 members want to dedicate this version to these authors who’ve died since ASTM STP 169C was revealed.
They’re Paul Klieger, Ed Abdur-Nur, Invoice Dolch, Jack Scanlon, Bob Philleo, Invoice DePuy, Bryant Mather, Ron Mills, and Owen Brown.
