What is a ready mix concrete plant?

Ready mixed refers to concrete that is batched for delivery from a central plant instead of being mixed on the job site.

What is ready mix concrete made of?

So what’s in ready mix concrete? RMC is a mixture of cement, water, and aggregates. Cement, the most important element of the mix, is the ingredient that lends concrete its resistance. Water is the vital fluid of the mix.

What ingredients are used for the production of portland cement?

The chief chemical components of portland cement are calcium, silica, alumina and iron. Calcium is derived from limestone, marl or chalk, while silica, alumina and iron come from the sands, clays and iron ore sources.

Can fly ash replace portland cement?

Typically, 15 percent to 30 percent of the portland cement is replaced with fly ash, with even higher percentages used for mass concrete placements. An equivalent or greater weight of fly ash is substituted for the cement removed. The substitution ratio for fly ash to portland cement is typically 1:1 to 1.5:1.

What is a batch plant used for?

A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete. Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement.

What is a batch concrete mixer?

Batch Concrete Mixers. Batch mixers are widely used machines for concrete mixing. Concrete mix obtained by this mixer is collected batch by batch and time by time. So, it is called as batch mixer. After pouring all the materials into pan or drum, it mixes all of those for some time and finally discharges.

What is ready mix used for?

Ready-mixed concrete is used in construction projects where the construction site is not willing, or is unable, to mix concrete on site. Using ready-mixed concrete means product is delivered finished, on demand, in the specific quantity required, in the specific mix design required.

What is Portland cement used for?

Basic use. Use Portland Cement in concrete for bridges, walls, culverts, floors, pavements, sidewalks, pipe, railway structures, reinforced concrete buildings, tanks and reservoirs, as well as for masonry units and other precast products.

What is the difference between Portland cement and regular cement?

Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver.

What is Portland cement used in?

Portland cement is an excellent building material generally used for its excellent binding properties giving strength to structural elements. Portland cement is most commonly used for the production of concrete. It is also used as a basic ingredient in the mortar, stucco, and non-specialty grout.

Is potash used in concrete?

Weak tensile strength is also the reason concrete additives like fiber and potash are used to supplement concrete mixes. As such, it is as important to understand reinforcing materials as it is to understand concrete mix ratios. Rebar is the most common reinforcing material and provides the most strength in concrete.

How does a concrete batch mixing plant work?

Mixing unit – This is the most critical part and heart of the concrete batch mixing plant. The job of the mixer is to receive all the ingredients and mix them thoroughly for a fixed time. Then it will discharge the contents into a transit mixer or a concrete pump. Air compressor – Air compressor is one of the important components here.

Moreover, there are standard ready mix concrete plants but these are usually modified to accommodate for certain situations. Concrete that are produced as per established procedures in batching plants and after that delivered to construction site by truck on which transit mixture is mounted is called ready mix concrete.

What is the difference between wet batch and dry batch concrete?

This means that different component of concrete mixture such as cement, aggregate, and water is mixed in the system. Comparatively, the output of wet batch concrete plant is greater than dry batch concrete plant that is why it is frequently seen as large plants.

What is a central batching plant?

It is also called central batching plant where the concrete is thoroughly mixed before loading into the truck mixer. Sometimes the plant is also referred as wet-batch or pre-mix plants. While transporting the concrete, the truck mixer acts as agitator only.
