This paper presents the experimental study on the control of the heat of hydration of mass concrete using the concrete bio-admixture, bioconc. The basic issue of mass concrete is thermal cracking, because of the heat of hydration of the cement content in mass concrete. This paper reports on the research results of using the concrete bio admixture, bioconc as a micro filler. To control the heat of hydration of mass concrete the cement content was reduced significantly up to 40 percent. The product is called bioconc low heat concrete. In order to control the researched object, it was compared with: pre-coolingmasscon and fly ash based low heat masscon. There were three parameters to be compared for asessing the product: hydration heat control effectiveness, cost of raw materials and the environmental impact. In this research, the concrete was made with fc' 25 and the size of the mass concrete mock-up was 1000x1000x2500 mm3. Research result written in series of following data: the peak temperature, duration to reach peak temperature, thermal gap between core-edge off masscon and masscon raw material cost. The peak temperature at bioconc low heat concrete was 63.5 C within 29.5 hours after pouring. It has thermal different at 19.5 C. The cost of material was US$ 54.6 per cubic meter.
