The reason for workers to prefer volume batching in general construction is that volume batching which involves measuring the volume of the ingredients (cement, coarse and fine aggregates, etc.) is easier, simpler and faster, whereas weigh batching involves tedious work- transporting the mixtures to weighing machines,weighing; if it exceeds the desired amount, it has to be unloaded etc. And moreover labourers at work sites are not technical and hence they tend to ignore complicated processes. If I am at work site I would do the same, though I'm an engineer.
Yes, lead can be added to concrete, typically to enhance its density and radiation shielding properties. This is often done in specialized applications, such as in the construction of radiation protection barriers in medical or nuclear facilities. However, due to lead's toxicity and environmental concerns, its use in concrete is heavily regulated and generally discouraged for general construction purposes. Alternative materials are often preferred for similar benefits without the health risks associated with lead.
depends greatly what is going over the concrete, Carpet is pretty forgiving, wood & stone not so much as a general rule 3/16 high to low within 10' is considered pretty reasonable

The normal slump of concrete typically ranges from 4 to 6 inches (100 to 150 mm) for general construction purposes. This slump measurement indicates the consistency and workability of the concrete mix; a slump within this range is often considered ideal for achieving a good balance between strength and ease of placement. However, specific project requirements may call for variations in slump, depending on factors like the type of structure and environmental conditions.
I WOULD DARE TO SAY THAT THIS IS AN OVERALL GENERAL QUESTION THAT DOES NOT HAVE A SIMPLE ANSWER. FIRST, WHAT TYPE OF CONSTRUCTION (MASONRY, FRAMING, ETC.)? AND AT WHAT LEVEL?

The IS code for columns in structural engineering typically refers to the Indian Standard (IS) codes that provide guidelines for the design and construction of concrete structures. The relevant IS code for reinforced concrete columns is IS 456:2000, which covers the general requirements for plain and reinforced concrete. Additionally, IS 3370 may be referenced for durability aspects. These codes ensure safety, stability, and serviceability in design and construction practices.
Get several years of experience as a laborer in general construction and learn as much as you can about all aspects of building construction -- carpentry, concrete work, electrical work, interior finishing, heating and sheet metal, and so on.
Concrete evidence is specific and fact-based, although general evidence is vague and and possibly an opinion.
Most concrete masons worked for concrete contractors or for general contractors on projects such as highways, bridges, shopping malls or large buildings such as factories, schools, and hospitals
