Sand is added to cement, stones and water to make concrete. A common form of sand is composed of silica. Silica is a macromolecule. The bonding in silica is shown in the image below: Use your understanding of the bonding in a macromolecule to explain why silica has a very high melting point.

Waste Management for Green Concrete Solutions: A Concise
Reinforced concrete based on ordinary Portland cement (OPC) is one of the most commonly used materials in modern buildings. Due to the global growth of the building industry, concrete components have been partially or completely replaced with waste materials that can be used as binders or aggregates. Besides the ecological The solutions in this guide will be useful for concrete producers and cement manufacturers, as well as developers, designers, contractors, and policymakers. The information contained in the guide will help each stakeholder advance climate-conscious innovation in the construction sector.Concrete Solutions Guide RMI

The other components of concrete the bigger stones and sand particles (aggregates) produce much less carbon, so when cement is mixed into concrete, its carbon emissions per kg are actually fairly low at 0.1 kg carbon per kg of cement. ‘That is, in a way, quite sustainable,’ says Veronica Ferrandiz-Mas, who works on innovativeCement is the most important component of concrete. One tonne of cement produces 1 t of carbon dioxide, accounting for around 7% of total carbon dioxide released each year .

According to the Center for Climate and Energy Solutions, carbon utilization in concrete will have a $400 billion global market by 2030. Several companies, like Solidia Technologies and Carbon Cure, are getting ahead of the curve by designing cement and concrete that utilize and consequentially sequester CO 2 during the Cement materials, including cement paste, mortar, and concrete, are the most widely manufactured materials in the world. Their carbon footprint is similarly hefty: The processes involved in making cement contribute almost 6 percent of global carbon emissions.

Pore Solution an overview ScienceDirect Topics
Pore solution is defined as the alkaline solution present in the pores of hardened concrete. The pH of this solution in OPC is in the range from 13 to 13.8 due to the dissolution of the variable amount of Na 2 O and K 2 O present in the different cements. 2 Portlandite, Ca(OH) 2, is formed during the reaction of the cement with mixing water and200 ML of CLEANFLO STEELCARE per bag of Cement for Mild & Moderate Environment and 250 ML per bag of Cement for High Chloride Environment.
