Sep 05, This paper studied the effect of aggregate properties on the crushing strength of concrete In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test And the test results show that concrete made from black stone has the highest workability followed by shingles stone & brick khoa of aggregat.

Jan 01, Compressive strength of hardened concretes made from recycled concrete coarse aggregates was studied as a function Of the compressive strength of original concretes from which the coarse aggregates were derived Also studied were properties of fresh concretes made from recycled aggregates, gradings of crusher products, properties of recycled.
While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk aggregate, and performance of aggregate in concrete.

Coarse aggregates are any particles greater than 019 inch, but generally range between 3/8 and 15 inches in diameter Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed.

composed of five ingredients: cement, coarse aggregate, fine aggregate, water, and air Normal concrete compressive strength requirements of psi forresidential concrete and psi (or higher) in commercial structur The purpose of the recycled materials in this study is to.
concrete and also the durability , strength, thermal properties, and density of hardened concrete This Bulletin describes types of aggregates normally used in concrete, aggregate properties affecting performance of the concrete, tests used to measure aggregate properties, and methods used to obtain test sampl Normalweight as well.
Crushing Value Test Form the result of crushing value we come to know that the Electronic waste is having more resistance to the wear and tear than the natural aggregate Result of Crushing value test is given below in table no1 Table - 1 Aggregate Crushing Value Aggregate Crushing Value Natural Coarse Aggregate % Electronic waste 235%.
This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented The proportions of replacement were 0%, 50%, and by mass of aggregat.
Jun 30, Thus, CCA—combined with the fine aggregate or “dust” from the crushing process—has a higher demand for water and cement, resulting in the potiental forgreater shrinkage and lower strength Because the crushing process produces concrete aggregate with jagged edges and dust, the resulting concrete was considered too harsh for applications.
When we design mix the concrete, its target strength is much less than the compressive strength of the aggregates used in the formation It can also be clearly seen in the mix design procedure that greater the maximum size of coarse aggregate use.
blast-furnace slag is also used as fine or coarse aggregate The aggregates are usually washed and graded at the pit or plant Some variation in the type, quality, cleanli-ness, grading, moisture content, and other properties is expected Close to half of the coarse aggregates used in portland cement concrete in North America are gravels;.
Concrete mixes were prepared using locally available river sand Ordinary crushed stone with size 20mm was used as coarse aggregate in concrete mix They generally possess all the essential qualities of a good building stone showing very high crushing strength, low absorption value and least porosity.
