Correlation between 28-day and 6-hour compressive strengths

That griping and predicting concrete strength is crucial importance for shorten design cycle of cement concrete proportion and control efficiently key construction node in time. The paper exposited systematically experimental method of strength estimation of cement concrete and corresponding research progress at present, and the prospect was also analyzed. It is very necessary to promote research work of experiment and analysis method because strength estimation of cement concrete is paramount. It has important meaning for delving into the aspect through above discussion in the future.

Each year a substantial body of literature is published on the use of microwaves to process cement and concrete materials. Yet to date, very few if any have lead the realisation of a commercial scale industrial system and is the context under which this review has been undertaken.The state-of the-art is evaluated for opportunities, and the key barriers to the development of new microwave-based processing techniques to enhance production, processing and recycling of cement and concrete materials. Applications reviewed include pyro-processing of cement clinker; accelerated curing, non-destructive testing and evaluation (NDT&E), and end-of-life processing including radionuclide decontamination.

“…Vitrification point of polymethyl methacrylate can reach 104℃ because its resistance to heat is not high. Performance polymethyl methacrylate is very fit to promoting curdle experiment request of microwave heat compared to other materials [5][6][7][8]。So it was used in this experiment that it is 10mm polymethyl methacrylate of plank shape. Concrete sample mould of 100mm×100mm×100mm were made applying in both pasting method and insert method.…”

In order to shorten time-periodic of mix design and verification of cement concrete in the period of construction, and can realize the node control of key procedure of cement concrete structure. The paper obtained and established relationship between super-early-stage strength and compressive strength of 7d, 14d and 28d of cement concrete on based of microwave promoting curdle. The method can realize predication of cement concrete through microwave promoting curdle.
