Concrete Cube Test- Competition - 2019

Closing Date: 31 Jan 2020(refer Contest Link) Reward: Certificate and Recognition

Contest outline:

All India Concrete Cube Test- Competition - 2019 is in the third Edition which is organized by Indian Chapter of American Concrete Institute (IC-ACI). IC-ACI invites students from colleges / institutes of civil engineering to participate in the All India Concrete Cube 2019 test competition.

About IC-ACI:

Indian Professionals- exchange information and dissemination of knowledge about concrete technology with USA from the early days of 20th century even before there was ACI. ICACI Chapter,established on 26th December,1979, has today an All India membership of more than 2,000 individual and organizational members.

Through its continued and tireless services in organizing seminars, workshops, symposia technical meetings with professional Bodies,special lectures by experts on selected topics and site visits, the Chapter has attained a rare distinction from ACI, USA, as Outstanding chapter for successive years. It was also acknowledged with 'Outstanding International Activity' in 1984 and "Excellent

Chapter Award" in 2000 through 2019.

The Chapter-has a rich technical library for professionals and research scholars, conducts certification course for 'Construction Supervisors', publishes quality journal and special technical publications to provide information on developments in the field of concrete technology, held annual competition for excellence in concrete through tests of concrete cubes, gave away tri-annual award of outstanding concrete structures and holds interactive meetings with BIS for updating of codes. It is striving today to improve the practice of concrete technology to new heights in the country.

Problem to be solved:

• Concrete is the most common and versatile construction material. Those who deal with concrete need to have 'Hands on' experience and genuine feel of concrete making, to understand its quality and behavior.

• Concrete making with variations in characteristics of cement, proportioning of aggregates, chemistry of material and chemical admixtures, control of water binder ratio, is a challenge to any civil engineer.The India chapter of ACI wants to encourage young Students of Civil Engineering to experience through this competition, the art and science of producing good quality concrete.

Rules and Guidelines for contest and design:
