Jignesh,  

I had a cursory glance at the report you mentioned in trailing mail.  

If you look at the compressive strength results of concrete without fly ash and varying % of fly ash (Fig 4.5) , irrespective of the % of fly ash, the compressive test results at room temperature are significantly lower at 56 days than they are at 28 days. Seems incredulous, no?  

I think we should stick to reports in reputed journals as I am afraid there is not adequate review of Thesis reports. It is indeed an unhappy comment to make.  

regards,

Alpa

Dear All,

Some experimental work done in India on this topic is available http://dspace.thapar.edu:8080/dspace/bitstream/123456789/144/1/8042306.pdf.

The results show that there is reduction in Compressive and Tensile capacity and Modulus of elasticity at Higher temperatures.

Regards,

Jignesh V Chokshi
