Concrete Batching, Mixing, Placing and Compaction of Concrete
Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...

In this method, quality control of concrete is easy as the batching and mixing of concrete is done at the mechanized central batching plant. This method of mixing is very useful for several places i.e. in congested area, at night concreting work, at large construction site etc.
Concrete Batching - an overview | ScienceDirect Topics
The electric mixing equipment is the most significant contributor to the emissions generated by concrete batching. It has been demonstrated in an internal review by a large concrete manufacturer that substantial improvements can be made to the efficiency of batching equipment by commissioning independent electrical contractors to report on the efficiency of batching equipment and making ...
How to Make Concrete – Batching, Mixing, Transporting & Placing
However, for producing ready-mix concrete, the mixer can well mix in about 15 to 30 secs. Concrete mixer having one cubic meter capacity high-speed Pan Mixer takes only about 2 minutes for batching and mixing. The RMC batching plant takes about 12 minutes to load a transit mixer of 6 m3 capacity. e) Transporting Concrete
Batching and Mixing of Mortar And Concrete Ingredients
The quality of concrete mixes is far superior if prepared by batching and mixing in microprocessor controlled batching plant than in small conventional mixers. The quality and speed of concrete production are much superior if manual controls and workforce are avoided or reduced.
Know more about concrete mix design (CMD). Once concrete mix design is carried out, the first task is batching of concrete materials like cement, aggregates, admixture, etc. The batching of concrete is done by measuring and combining required concrete ingredients either by weight or by volume as per the mix design.

How to Properly Mix Concrete (DIY) | Family Handyman
Work it to the perfect concrete mix ratio. If the mixed concrete looks like the mix in step 9, it's ready to pour. Otherwise, mix in additional dry mix or water until you get the right consistency. It's tempting to just squirt water into the dry concrete mix with a hose and mix up a soupy batch of concrete.
When you mix concrete properly, it ends up with a consistency that has been compared to cookie dough. To test the consistency, use the blade of your shovel like a knife and try to cut a shallow channel through the surface of the premix concrete. If it is too dry, the channel walls will be crumbly; add more water and mix the concrete further.
