Concrete – Characteristic, Compressive and Flexural Strengths

(Out of the several important properties of concrete as mentioned in this write up, the compressive strength  governed by many factors / actions,  that are responsible for the quality of concrete from raw material quality to QAQC efforts to placement and testing of the concrete,  is taken as one single critical parameter, which determines the quality of concrete construction.)

General

The strength of concrete related terms are described in this wrote up, which are to great strength depends on managing the concrete quality.

Quality Assurance & Quality Control is a vast subject and must be understood by the management in the organisation, particularly the top management. It must be in built in all department of the organisations. (There exists interrelationship in actions of Programme Management, Portfolio Management and Project management departments). The project outcome (taken to generate goods, services, and results), fulfil the goals and objectives into reality. The project is temporary in nature – when ends, the operations begin.

And for a successful operation there must be built in quality in Project Initiation, project Planning, Project Execution, Project Monitoring & control and Project Closing. https://techconsults.in/project-management-framework-essentials-1/

There must be quality in mission and objective, so that the organisation acts as a unit of Total Quality People (TQP).

When assessing quality in real sense the ISO certification for the organisation and its implementation is very important. In short, the organisation must follow the two premises as below:

Decide what you want to do.

Do what is decided.

The above two actions cover all actions required for quality management – in all the units. This is applicable in fields as well where designs are translated to   real structures to create a real state.

As such all such precautions are necessary at projects in using concrete construction. IS 456 provides necessary guidelines for production, transport, placement and testing of concrete. The guidelines must be given full attention by TQP, which includes construction and supervision staff. A quality output is the dedicated effort of both, the construction and supervision staff.

The various types of concrete are used at various projects. The mix proportioning is done and tested in laboratory and in field, for different grade of concrete. Tests are carried out on concrete for materials, fresh concrete, and hardened concrete so that the output fulfils the required acceptance criteria

Project Quality and Management Processes

Out of the several important properties of concrete as mentioned in this write up, the compressive strength  governed by many factors / actions,  that are responsible for the quality of concrete from raw material quality to QAQC efforts to placement and testing of the concrete,  is taken as one single critical parameter, which determines the quality of concrete construction.

The strengths of concrete associated with properties of hardened concrete are discussed in brief as below:

Characteristic strength

Compressive Strength (f_ck) = Grade of Concrete (Defined as compressive strength of concrete specimen after 28 days of curing as M25, M30, M35, M40, etc.,)

The term “Characteristic strength “of concrete is one of the important properties of concrete accepted unanimously by design engineer or any other person involved in the construction sector.
