Concrete hollow block can be produced by concrete block making machinethe product is mainly used to fill the high-level framework of the buildingbecause of its lightweightsound insulationgood thermal insulation effectthe majority of users trust and favor.The raw materials are as bellows: Cement. powdery hydraulic inorganic cementitious material.
In this article we explore the importance of aggregate testingvarious tests on aggregates and all the important properties of aggregates. Aggregate is one of the primary building materials and constituent of concrete. Aggregates are used in construction and include sandgravelcrushed stoneslagrecycled concrete etc.
Feb 282008 There are organic soils toobut they arent appropriate to use as a bedding material for concrete and should be removed (see Table 1). Coarse-grained soils include sand and larger aggregate particleswith sand sizes typically ranging from 0.003 to 0.08 inches in diameter and aggregates as large as 1 inches.
Sep 032017 The choice of aggregate is determined by the proposed use of the concrete. Normally sandgraveland crushed stone are used as aggregates to make concrete. The aggregate should be well-graded to improve packing efficiency and minimize the amount of cement paste needed. Alsothis makes the concrete more workable.

In other wordsthe machine used for mixing concrete is known as the mechanical concrete mixeror in simple wordsthe concrete mixer. Concrete mixer is used to mix cement with aggregates including sand or graveland water to form concrete. The concrete mixers must not only achieve the uniformity of the mixbut they should also discharge the
This gives a stronger and denser concrete. Rounded aggregates give a more workable mix. Angular aggregates make concrete harder to placework and compactbut can make concrete stronger. STORAGE Aggregates should be stored where they will stay cleanseparated from other materials and dry. If the aggregates are very wet use less water in the mix.
Coarse aggregates are any particles greater than 0.19 inchbut generally range between 38 and 1.5 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 pitriverlakeor seabed.

The term concrete aggregates covers a variety of productsbut are usually summed up as stone and sandin coarse and fine grade. Coarse aggregates are defined as any material greater than 4.75 mm. A coarse aggregate is also identified as any aggregate retained in a 4 sieve.
Oct 012016 Engineering Properties of Aggregates. Aggregates are used in concrete to provide economy in the cost of concrete. Aggregates act as filler only. These do not react with cement and water. But there are properties or characteristics of aggregate which influence the properties of resulting concrete mix. These are as follow. Composition; Size & Shape
1) EPS: Expanded Polystyrene plays a very unique role in concrete. Research has shown that concrete with this material behaves very similarly to light weight concretes containing traditional aggregates. This is believed to be the case because the
