Electrochemical monitoring of open circuit potential and compressive strength effect of the different concentrations of these admixtures in steel-reinforced concretes immersed in the acidic/marine-simulating environments were analysed for detailing admixture performance.
The chemical structure of the superplasticizer can be tailored based on the required admixture performance.
Silica fume (SF) as a mineral admixture for high performance concrete produces more discontinues and impermeable pore structure in concrete.
This study suggests that biochar from wood waste has the potential to be deployed as carbon sequestering admixture to improve performance of cementitous mortar.
Fly ash, when used as mineral admixture in high performance concrete, can improve both the compressive strength and durability properties of the concrete but the disadvantage is long setting time and a slower early strength development.
This model has been used primarily to evaluate the influence of population subdivision and admixture on the performance of the transmission-disequilibrium test (Ewens and Spielman 1995) and to examine linkage disequilibrium statistics (Guo et al. 2005).
