Accelerating early strength development of concrete using metakaolin as an admixture
Santrauka
A study of metakaolin (MK) as an early strenght accelerator for Portland cement (PC) and Portland Cement-Pulverised Fuel Ash (PFA) concrete (PC-PFA) has been carried out. This paper reports strenght development, particularly at early curing ages, to evaluate the effectiveness of MK as an accelerating admixture. This is supported by analysis of the heat evolution using a calorimeter. [...].
