Strength of concrete Chapter 6 Properties of concrete :- Strength Durability Impermeability Volume stability Strength of concrete is the most valuable property. What is strength? Strength depends on the physical structure and volume of hydration products. Therefore it gives an idea of the quality of concrete. Note :- strength depends less on the chemical composition of the paste and more on the physical structure

by researchers on how to minimize or be free in concrete deterioration in an economical way and some are using high-cost materials to defend against deterioration and until now researchers are still searching for the finest and low-cost method yet effective to utilize. Deterioration due to chemical weathering in concrete structures is one of the major problems in construction that makes concrete weakened‚ unstable‚ and even steel within the concrete will be deteriorated and can make serious trouble

gravel‚ or crushed stone that‚ along with water and Portland cement. Aggregates are essential ingredient in concrete. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates‚ which account for 60 to 75 percent of the total volume of concrete‚ are divided into two distinct categories - fine and coarse. Fine aggregates generally consist of natural sand

A. Study Of Compressive Strength Of Concrete By Partial Replacement Of Cement With Marble Dust Powder[4] Abdullah Anwar‚ Juned Ahmad‚ Meraj Ahmad‚ Khan Sabih ‚ Ahmad Syed ‚ Aqeel Ahmad Abdullah Anwar & his teammates stated that marble dust powder is now days intensely focused research topic in which many problem related to environmental well as civil engineering are associated. They stated that Marble dust powder is settled by alleviation then drop away‚ which end up in environmental contamination

this study. Library visit and internet surfing were also conducted. The result of this study revealed that all samples from Basud‚ Dagotdotan and Dogongan would pass the sieve analysis test requirements base on ASTM C-33 standard specification of concrete aggregates except the fine aggregates from Alawihao quarrying site. Bulk specific gravity SSD and OD of coarse and fine aggregates of all sites considered would not satisfy the ACI Standard. With the four sites considered‚ only apparent specific

alkaline solution. Geopolymer concrete has significant advantages over standard concretes such as resistance to corrosion and fire‚ high compressive and tensile strengths and also less shrinkage. The development of geopolymer concrete is an important step towards the production of environmental friendly concretes. The purpose is apparently to reduce the carbon dioxide emission resulting from the production of Ordinary Portland Cement (OPC). The production of geopolymer concrete mostly relies on the curing
