Abstract. Limestone powder (LS) is one of the mineral materials in concrete due to its wide availability and low cost. This paper discusses effects of LS on the workability, setting time, shrinkage, mechanical properties and durability of concrete. Such effects are mainly influenced by many factors, including the particle size and content of LS ...

The results indicated that replacing anhydrite with limestone powder in SCGM can improve the flowability, shorten the setting time, and enhance the compressive strength at early and late stages. When the replacement rate of limestone powder was 20%, the compressive strength of SCGM for 6 h and 28 days increased by % and %, respectively.

The main objective of this experimental work is to investigate the effect of partial replacement of cement with limestone powder on the permeability of concrete, especially in severe curing conditions. For this evaluation, 5%, 15% and 30% cement of concrete mix design were replaced by limestone powder and two different curing conditions applied to the concrete samples. Some of the concrete ...

In the study, limestone dust was fixed at 9%, and expansive soil was replaced with fly ash by (5%, 10%, 15%, and 20%). According to the results, 15% of fly with 9% of limestone dust can be used for stabilization of such high expansive soil. Ogila [ 11] studied the effect of adding limestone dust (passing sieve #200) to very high expansive soils.
