17-09-2019· The Process of Machine Mixing of Concrete: First of all, wet the inner surfaces of the drum of concrete mixer. Coarse aggregates are placed in the mixer first followed by sand and then cement. Mix the materials in the dry state in the mixing machine. Normally it should be 1.5 to 3 minutes.
AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 µm (No. 200) sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.).

Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70 to 80 % of total volume of concrete. So, we can say that one should know definitely about the aggregates in depth to study more about concrete. Classification of Aggregates as per Size and Shape
11-08-2018· Aggregates are one of the most important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 60 to 80 % of total volume of concrete. So, we can say that one should know definitely about the aggregates in depth to study more about concrete. Aggregate may be natural, […]

The suitability of the fine sand of zone 4 for use in reinforced concrete should be tested. For sands, the sand content of the mix should be low whose greater part is smaller than 60C micron. In general, finer the grading of the fine aggregate, higher should be the coarse/fine aggregate ratio. Typical values are shown in Table 4.23.

08-06-2017· Aggregate is a granular material, such as sand, gravel, crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water; it has been customary, therefore, to treat it as inert filler in concrete and mortar.
01-08-2019· 2. According to the function, it is divided into crushing type and sand making type: the concrete crushing and screening machine includes a combination of crushing equipment such as jaw crusher, cone crusher and impact crusher. The sand making type is mainly equipped with sand making machine and hammer sanding machine.
with an increase in the top size of the aggregate provided the aggregate is well graded and mix can be thoroughly consolidated in the machine. Almost all concrete block producers today use aggregate smaller than ½ inch although scattered reports have indicated the feasibility of using an aggregate with some material of larger size. The maximum size
Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an 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.
When fine particles are in proper proportion, the sand will have fewer voids. The cement quantity required will be less. Such sand will be more economical. Demand for manufactured fine aggregates for making concrete is increasing day by day as river sand cannot meet the rising demand of …
08-07-2021· Aggregates are the most basic material used in construction. They provide the foundation for roads, bridges, and buildings, while also making up over 90% of an asphalt pavement and up to 80% of a concrete mix. On average, 38,000 tons of aggregates are necessary to construct one lane mile of interstate highway.
01-10-1995· Their results indicate that lateritic aggregates are suitable materials for making con- crete despite their slightly inferior performance compared with that of igneous aggregates. Adepegba [2] reported that locally occurring stable latite can be used to replace sand in normal concrete to form laterized concrete.
Youcef Ghernouti et al. 1 The study present the partial replacement of fine aggregate in concrete by using plastic fine aggregate obtained from the crushing of waste plastic bags. Plastic bags waste was heated followed by cooling of liquid waste which was then cooled and crushed to obtained plastic sand having finesse modulus of 4.7.
The synthetic aggregate for use in concrete is a composite material of recycled plastic having a filler encapsulated in the plastic. The synthetic aggregate includes between 30% and 50% recycled shredded plastic, the balance being filler. The plastic may be linear low-density polyethylene (LLDPE). The filler can include red sand, fly ash and quarry fines.
