quality control of fresh concrete. This is not applicable to Self-Compacting Concrete, as it is not evaluated by slump testing. 1.2 Definitions (Terminorogy) The definitions of terms used in this Recommendation are as follows. (1) Self-Compacting Concrete
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.
concrete and; (3) testing of concrete in tension and compression. For the mix design of concrete (ASTM C192), 2.5kg of water was mixed with the cement, sand and gravel (each having a mass of 6 kg) with 500g added at intervals. The mixture was done by hand for about 20 minutes using a shovel and wheelbarrow. After mixing the concrete, the slump
The reality is that if we measure the slump, the only thing we really know at this point is the slump. The slump of a concrete mix is influenced by everything. Changes in any of the following can change the slump of the concrete:

self-compacting concrete reduces t he dosage of superplasticizer needed to obtain similar slump flow as for concrete made with Portland cement only (5). Also, the use of fly ash improves rheological properties and reduces cracking of concrete due to the heat of hydration of the cement (6). Kim et al. (7)
No-fine concrete is produced by using ordinary Portland cement, coarse aggregates, and water. This concrete is tested for its properties, such as slump value, porosity and compressive strength.
