Description

This book provide the basic principles and sufficient information on the state of art relating to all
facets of manufacturing and production processes in the making of structural concrete. To cater
to the needs of the undergraduate level courses, more emphasis is laid on the fundamentals
and practice.
Entire book has been revised as per the revisions in various B.I.S. codes related to Cement,
Sand, Aggregate, Concrete Mix Design, etc. The chapter on Concrete Mix Design is entirely
rewritten. A large number of Multiple Choice Questions have been added in each chapter.
In addition to the traditional concrete technology topics dealing with the principles of concrete
and concrete – making materials, the current state of the art of self compacting concrete, special
concretes, concreting techniques, non-destructive testing (NDT), repairs and strengthening of
concrete structures, fly ash concrete, etc. has been included.
The book incorporates relevant information on numerous Indian standard specifications and
code of practices relating to cement and concrete including the latest revision of IS: 456–2000.
The entire subject matter is canvassed in the chapters like Cement; Types of Cement; Testing
of Cement; Aggregates; Water for Construction; Admixtures; Fresh Concrete; Production of
Concrete; Strength of Concrete; Elasticity, Creep and Shrinkage; Durability of Concrete; Testing
of Hardened Concrete; Quality Control of Concrete; Concrete Mix Design; Special Concretes
and Concreting Techniques; Repair and Rehabilitation of Concrete Structures; Fly Ash Concrete.
The book now Contains:
194 Self explanatory neat diagrams
140 Useful tables
18 Worked Examples
212 Short Questions with Answers
287 Objective Questions
229 Exercise Questions.
The book should prove to be extremely useful to the Civil and Structural Engineering students
preparing for the Degree Examinations of all the Indian Universities, Diploma Examinations
conducted by various Boards of Technical Education, Certificate Courses as well as for the
A.M.I.E., U.P.S.C., G.A.T.E., I.E.S., R.R.B. and other similar competitive and professional
examinations. It should also prove of interest to the practising professionals
