Traditionally, the acceptance for new construction has been limited to judging the acceptability of the concrete delivered to the project on the basis of slump, air content, and compressive strength. In common practices,compressive strength of the concrete is evaluated using the destructive tests (on Cube/Cylinder) which is time consuming, cumber some and labour intensive. The Maturity Method, proposed in this proposal is a non- destructive and proven method for estimating the strength of newly placed concrete.The Maturity Method is a technique to estimate in-place strength by accounting for the effects of temperature and time on strength development. This system improves the estimation of strength of concrete structures and accelerates the work flow in large constructions. This capability, among others, enables quality control engineers to determine the appropriate time to remove forms and begin new construction. Also we can open the pavements for traffic.
In Precast it would prove a boon which may ultimately increase the production of the elements as “Turn-Around Time” is potentially reduced in prefab plants with the use of Maturity Method.The research aims at developing a practical and economically viable mobile phone based Maturity Meter technology along with its Calibration and Validation protocol for the industry. The researchers plan to implement a unique concept of “Web Based Module” to generate maturity curves that can predict the concrete strength in real-time. The data would be stored in SD card placed in Maturity Meter. Also GSM module will send messages on registered cellphone and the site engineer would be able to decide about removal of forms. It will lower the production cost by optimising the mix design around in place strength targets. Reduce or eliminate dependence on highly variable test samples for determining early-age concrete strength.
