Abstract EN
The aim of this work is to know clearly the effects of temperature in response to curing condition, hydration heat, and outside weather conditions on the strength development of high-performance concrete.
The concrete walls were designed using three different sizes and three different types of concrete.
The experiments were conducted under typical summer and winter weather conditions.
Temperature histories at different locations in the walls were recorded and the strength developments of concrete at those locations were measured.
The main factors investigated that influence the strength developments of the obtained samples were the bound water contents, the hydration products, and the pore structure.
Testing results indicated that the elevated summer temperatures did not affect the early-age strength gain of concrete made using ordinary Portland cement.
Strength development was significantly increased at early ages in concrete made using belite-rich Portland cement or with the addition of fly ash.
The elevated temperatures resulted in a long-term strength loss in both belite-rich and fly ash containing concrete.
The long-term strength loss was caused by a reduction in the degree of hydration and an increase in the total porosity and amount of smaller pores in the material.
