The influences of dispersing agent and additives for cement, including mineral and chemical admixtures, were evaluated for a total of 18 different combinations.
Due to its properties, surfactants are widely applied in several industries, from laundry, to surface cleaning, additives for cement, cosmetics, pharmaceutics, agriculture, food industry and in oil industry (2).
"We need specifics, for drilling additives, for cementing additives, and for perforation chemicals," Ernst said.
The quantities of fines used were calculated to account for the total value of the absolute volume of the mixture in cement substitution, which implies that fine scoria can be surely used as an additive or substitute for cement in concrete mixtures (Al-Chaar et al. 2011).
This study investigated two artificial materials biomass fly ash (AFA) and a new synthesized composite from clay and silica gel waste (CSG as additives for Portland cement.
Sugarcane biomass waste can replace the silica flour as an additive for oil well cement, resulting in improved compressive strength and permeability of the slurries.
Among all, nano-silica has been proven an effective additive to cement matrix for accelerating cement hydration due to its high reactivity, ability to refine the microstructure and thus, leading to a reduced porosity (Toutanji et al. 2004).
Both would allow certain types of "beneficial reuse," or recycling, of coal ash as an additive in cement, concrete and asphalt, for example.
The objective has been to evaluate the pozzolanic properties of bottom ash as an additive in cement, as it has been demonstrated in the case of fly ash for many years.
Use of inorganic additives such as cement for rammed earth walls has been in practice since the last 5 6 decades and cement stabilised rammed earth (CSRE) buildings can be seen across the world.
Compression index decreased with amount of additive in contrast with previous finding for cement treated samples of a low plastic clay soil.
