Description:FIELD OF THE INVENTION
The present invention relates to a blended cementitious binder composition and a method for preparing the blended cementitious binder composition. More specifically, the composition through specific mixing and hydration processes to achieve a homogeneous blend suitable for various cementitious applications, including concrete and mortar formulations.

BACKGROUND OF THE INVENTION

According to the Paris Agreement represents a landmark framework for international climate action, uniting countries in the pursuit of strategies to combat and adapt to climate change. Cement production stands out as a major contributor to anthropogenic CO2 emissions, primarily attributable to its reliance on calcium-based hydraulic cements, particularly Portland cement. The calcination process involved in cement manufacturing results in significant CO2 emissions due to the thermal decomposition of limestone (calcium carbonate) into lime (calcium oxide) and carbon dioxide, alongside emissions from the combusti , Claims:We claims

c. at least one silica-bearing material derived from industrial waste, in an amount ranging from 15% to 30% by weight;
d. at least one hydrating agent, in an amount ranging from 2.5% to 5.0% by weight.

2. The blended cementitious binder composition as claimed in claim 1, wherein the cement is selected from Ordinary Portland Cement , Portland Pozzolana Cement, Rapid Hardening cement, extra Rapid Hardening Cement, Quick Setting Cement, Low Heat Cement component is present in an amount ranging from 25% to 50% by weight of the total binder composition.

3. The blended cementitious binder composition of claim 1, wherein the calcined magnesite is obtained through a calcination process conducted at a temperatur
