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 …

Compressive strength development curves versus lime stone content. The results of splitting tensile strength are illustrated in Fig. 2. At 3 days, the addition of limestone powder was shown to increase the splitting tensile strength, compared to OPC specimens. At 28 days, the splitting strength of the samples was as follows: OPC (4.30

The results showed that microwave curing at a power of 320 W for 5 min increased the 3-day compressive strength of heat-stored LC 3 by 87.3 %, without adversely affecting the later-stage strength, thus compensating for the deficiency in early strength. Microstructure and pore structure analysis revealed that the enhancement of …
Strength values, used with rock mass data such as discontinuity information, are used to identify the most appropriate methods to extract building stone. Of the sites assessed, …
Limestone is widely used in the construction industry to produce Portland limestone cement (PLC) concrete. Systematic evaluations of hydration kinetics, compressive strength development, and ...
The dynamic compressive strength factor for the granite was less than 1; for the basalt, 1.35; for the limestone, 1.52; and for the tuff, 1.7^-« The compressional wave velocity of
Keywords: portland-limestone cement conc rete; hydration; co mpressive strength; carbonation; model 1. Introduction Portland-limestone cement (PLC) is manufactured by intergrinding Portland cement clinker with various contents of limestone. The limestone is more easily ground than clinker, and becomes concentrated in the finest particles.

The compressive strength results for the ternary mix with 45% replacement of OPC are shown in Fig. 2. While the dolomitic limestone based LC3 mix seems to be only marginally lower than the OPC mix at 7 days, the compressive strength at 28 days for the OPC mix is significantly higher than that of the two LC3 mixes.
