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 …

The use of limestone powder (LSP) as a cement replacement is used in abundant applications due to its low cost and wide availability. Adversely, the use of LSP as a part of the precursors of alkali-activated materials (AAMs) is still in the developing stage. This scarcity of studies opened the door and encouraged the researchers for more …

As shown in Fig. 4.2 most of the Portland limestone and composite cements conform to the 32.5 and 42.5 strength classes, although "very high strength" 52.5 Portland limestone cements are also produced. Most countries around the world specify similar chemical and physical requirements for the limestone that can be used, including a …

In 2008, the Canadian standard (CSA A3001-08 [21]) also introduced Portland-limestone cement with LS contents below 15% of total binder. Subsequently, Portland-limestone cement was designated as GUL (general use limestone cement) in CSA A3001-10 [22]. In 2012, ASTM C595 [23] also introduced Portland-limestone …

The steel industry imports this material from UAE, Oman, Malaysia, Vietnam and Iran. India has limestone reserves in Andhra Pradesh, Karnataka, Madhya Pradesh, Chhattisgarh, Bihar, Jharkhand, and Odisha but steel-grade limestone is limited to a few states only. The limestone requirement is about 100 kg per tonne of liquid steel produced.

Moreover, the limestone powder could be considered as a valuable component due to its ability to interact with tricalcium aluminate, resulting in the formation of calcium carboaluminate hydrates and facilitating the precipitation of C-S-H, and the inclusion of limestone powder expedited the hydration process of tricalcium silicate …

The composited cementitious materials usually have superior performance; for example, using limestone powder (LP) and fly ash (FA) as the admixtures of cement in concrete/mortar is a popular way of improving the properties of concrete/mortar structures. In this work, we performed experimental tests to study the hydration process and pore …

percent limestone powder improved the workability of the concrete mix. This can be attributed to filler properties of limestone powder, which, affecting the cement particle system, changed the ordinary distance between them and modified the water quantity available for the hydration process. These results proved that the bamboo fiber and
