almost every construction work requires cement. therefore, the composition of cement is a matter of great interest to engineers. for understanding cement composition, one must know the functionality of cement ingredients. by altering the amount of an ingredient during cement production, one can achieve the desired cement quality.
the indian cement industry is the second largest in the world after china, employing in excess of a million people throughout the country. the cement industry contributes a big deal to the indian economy, more so because the construction industry in india relies heavily on the cement industry
for the construction of buildings in our country , we can see number of advertisement of cement and steel . as advertisement is part of business we have to be careful while selecting cement and steel . different grade of cement available in our ma...

as india has a high quantity and quality of limestone deposits through-out the country, the cement industry promises huge potential for growth. according to clsa (institutional brokerage and investment group), the indian cement sector is witnessing improved demand.
cement is thought to be older than humanity itself, having formed naturally 12 million years ago, when burnt limestone reacted with oil shale. concrete dates back to at least 6500 bce when the nabatea of what we know now as syria and jordan used a precursor of modern-day concrete to build structures that survive to this day.
cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic
what factors led to the rapid expansion of cement industry in india? answer: factors that led to rapid expansion of cement industry are: decontrol of cement price since 1989. decontrol of distribution of cement since 1989. many other policy reforms led the cement industry to expand in capacity, process, technology and production.
cementing process: displacement design, job execution, cement volumes, cement material properties material properties: cement, relationships between pipe-cement-formation pressure and temperature changes/cycling over the life of the well geomechanics: in-situ stresses, change in stresses along borehole, change in stresses in cement and pipe
the u.s. used more than 122 million metric tons of portland cement in 2006, according to the portland cement association (pca), an industry group, and
portland cement gets its strength from chemical reactions between the cement and water. the process is known as hydration. this is a complex process that is best understood by first understanding the chemical composition of cement. manufacture of cement portland cement is manufactured by crushing, milling and proportioning the following materials:
why industry leaders choose vortex. vortex’s knowledge of dry bulk solid processing is unprecedented. since 1977, we have delivered innovative solutions to a wide range of industries handling thousands of dry bulk solids. if the product is dry, there is a high probability vortex has handled it.
they may be designed to maintain structural integrity for over four hours of fire exposure. concrete masonry is also used to protect the structural integrity of steel from fire exposure. 4. structural integrity: masonry can be used with all roofing systems, and it has excellent load bearing capacity for supporting roofs and additional floors.
concrete is part of the solution towards creating a net zero carbon society. learn more about the significant progress the industry is making to lower concrete’s carbon footprint through innovation and the outstanding sustainable buildings being constructed with the material.
there are the many reasons why concrete is a sustainable building material: long life - concrete structures are long-lived, such as pavements that have an average service life of 30-50 years. low life-cycle cost - concrete consumes minimum materials, energy and other resources for construction, and requires little to no maintenance throughout its service life.
• aggregates in any particular mix of concrete are selected for their durability, strength, workability and ability to receive finishes. • for a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine
why choose brick? clay brick requires virtually no maintenance, saves energy, reduces insurance costs, increases resale values, absorbs exterior noise and is the safest wall cladding for your home, providing better protection from fire, wind and hail.

pouring fresh concrete is a time-sensitive project and unexpected delays can cause major problems. with the use of admixtures, you can have more control over your concrete. admixtures can restore loads of concrete that might need to be rejected due to delays or other complications.

concrete contains quite a bit of trapped air (as much as 5–10 percent), because there is some space around the open, three-dimensional structure of cement hydrate crystals and the sand and gravel trapped between them. and that, in turn, explains why concrete can bend and flex, stretch and compress (just a little bit, anyway).
