Understanding Limestone in Cement| Concrete Construction

Mar 26, 2015· The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation

limestone Characteristics, Uses, & Facts Britannica

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil

Advantage of ternary blended cement Cement Science

The binary cement, e.g. Portland cement blends with slag or fly ash or limestone, has gained great popularity in many countries. However, each kind of binary cement has its own shortfalls, e.g. the addition limestone can reduce the later strength due to its dilution effect, while the reaction of slag is relatively slow in the early ages.
