(PDF) Limestone and Silica Powder Replacements for Cement: Early
Because limestone is the major source of calcium for cement production, as well as being on e of the most commonly employed aggregates, its presence is ubiquitous within the concrete industry [15].Li et al. [33] explored the effects of the clay content and characteristics, methylene blue value (MBV ranging from 0.35 to 2.5) of manufactured sand (MS) and the limestone fines content on the performance of concrete. Results showed that with an increase in MBV, the workability, flexural strength and 7-d compressive strength of the Clay in cement-based materials: Critical overview of state-of

Properties and behavior of limestone cement concrete and mortar
Limestone cement concretes indicate lower resistance to freezing and thawing compared with the pure cement concrete. Portland limestone cement, containing 20% limestone, shows the optimum protection against rebar corrosion. Furthermore, the limestone additions decrease the carbonation depth and the total porosity of the mortar.assess on cement production practice and potential cement replacing materials in Ethiopia to reduce the high cost of cement in order to provide sustainable and cost-efficient structure for the public and private sectors.

A review of low-carbon technologies and projects for the global cement
As a major greenhouse gas, large emissions of CO 2 contribute to the global greenhouse effect. In 2019, CO 2 emissions from cement industry reached 2.4 Gt, accounting for 26% of the total industrial emissions (IEA, 2020a), and the low-carbon development for the cement industry is extremely urgent.Over 90% of countries and regions world-wide produce The blue planet is becoming grayer by the day, as Earth is paved over with concrete.
