Since the last two decades, there has been immense boom in the amount of cement production by cement companies as well as its consumption in the country. India has already made its mark as one of the most prominent cement producers of the world.  Analysis of the Indian market had predicted a massive increase in the industry during the second half of the decade. The results exceeded compared to what was foreseen. For instance, according to the CapEx database of the Centre for Monitoring Indian Economy (CMIE), “an incremental capacity of a huge 68.5 million tonnes per annum(mtpa) would be covered during the time span of 2015-2018”, which did happen. In 2015 alone, more than 60% of the predicted production capacity had been successfully achieved. Initially, the amount appended to India’s capacity was 40.5 mtpa in the year 2015. After that, accommodation of 18.1 mtpa was under the process of installation by the end of the fiscal year 2016. The remaining amou...

Portland Pozzolana cement is manufactured by synthesising Ordinary Portland cement with a mixture of pozzolanic materials in uniform proportions. It is also known as PPC cement in short.  In this blog, we’re going to discuss the applications, properties, and characteristics of PPC in detail. Pozzolana or Pozzolanic material Pozzolana is a type of volcanic powder that is found near Mount Vesuvius in Italy. Pozzolanic material can also be processed artificially, with silica and alumina as the constituent particles. Naturally, this material does not contain any cement related properties. But when mixed with water, lime and calcium hydroxide, it reacts to form a compound that is cementitious. Artificial Pozzolana  Contains silica fume, rice husk, blast furnace slag, fly ash. Natural Pozzolana   Contains diatomaceous earth, pumice, burnt clay.  How does the manufacturing of PPC take place? The raw materials used here diffe...

With population and pollution growing every year, there is an urgent need to revamp the waste management processes being used. Landfills are now overflowing, and the incineration process consumes excessive energy while increasing carbon emission. The cement industry leaders have now come up with an idea of utilizing waste to fuel kilns used in cement production. Sustainability The term is used to express the need of sustaining ourselves without hampering the chances of future generations to meet their needs. Under the cement sustainability initiative the leading organizations in the cement industry work towards lowering the carbon emissions and consumption of non-renewable resources. Coal Consumption: Overview The supply of coal to the cement industry dropped to a mere 35% in 2013, from a whopping 75% in 2003. Currently, the cement industry gets only 5% coal from the production in the country, while the rest of its depends are fulfilled through imports. We i...

The most important step to maintain the strength of a concrete structure is to ensure that it does not develop cracks. One of the major problems that occurs due to the hardening of concrete is shrinkage cracks . It weakens the structure with time. So to ensure that it does not happen, concrete curing is performed. Curing is the process of ensuring that moisture stays on the concrete to avoid it from hardening and developing cracks. Due to proper hydration, the strength and durability of concrete structure also increases. Various concrete suppliers too emphasize the importance of curing to the buyers beforehand.  Curing takes place immediately after placing the concrete and deals with maintenance of the desired temperature and moisture for extended periods of time. Just after the structure has been constructed and the surface is hard enough, such that a person can walk on it without damaging the concrete, curing should be started then and there.  Methods of curing depe...
