Guide to Pouring Concrete
- Step 1 – Site Work. Before concrete can be poured, the site needs to be prepared to reduce the chance of heaving from expansive soils and frost.
- Step 2 – Forming.
- Step 3 – Mixing.
- Step 4 – Placement.
- Step 5 – Early Finishing.
- Step 6 – Troweling.
- Step 7 – Final Finishing.
- Step 8 – Curing.
What does concrete processing mean?
The production processes of conventional and nonconventional concrete involve the selection and preparation of source materials, the mixing and blending of raw materials (including cement binders) in controlled amounts, the delivery of blends either as slurries or dry mixes, and the placement of the mixes, usually as …
What are the 5 types of concrete?
5 Types Of Concrete You Should Know About
- Reinforced Concrete.
- Lightweight Concrete.
- High-Strength Concrete.
- High-Performance Concrete.
- Precast Concrete.
What are the 4 types of concrete?
The Types of Concrete
- Normal Strength Concrete. This concrete combines all the basic ingredients — concrete, sand and aggregate — using the 1:2:4 ratio.
- Plain or Ordinary Concrete.
- Reinforced Concrete.
- Prestressed Concrete.
- Precast Concrete.
- Lightweight Concrete.
- High-Density Concrete.
- Air-Entrained Concrete.
What is the formula for concrete?
Use the formula. Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.
What are the stages of concrete production?
The stages of concrete production are:
- Batching or measureme nt of materials.
- Mixing.
- Transporting.
- Placing.
- Compacting.
- Curing.
- Finishing.
How many main processes are there in producing concrete?
Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process. The two processes are essentially alike except in the wet process, the raw materials are ground with water before being fed into the kiln.
What are the 3 composition of concrete?
Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement.
What is the strongest concrete?
Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements …

What is the process of making concrete?
Proportioning. The key to achieving a strong,durable concrete rests in the careful proportioning and mixing of the ingredients.
How to make concrete?
1) Mix two parts all-purpose sand to one part of cement. Mix either fine or coarse all-purpose sand with the cement in a wheelbarrow with a shovel. 2) Add four parts of gravel or crushed brick to the mixture. Add four parts of gravel or crushed brick for every one part of cement. 3) Slowly add water to the dry ingredients. Fill a 5-gallon (18.9 l) bucket ¾ of the way with water and pour the water into the dry ingredients. 4) Mix the cement together. Use a hoe or a shovel to mix the water and dry concrete mixture together. Continue to stir the concrete mixture together until it’s stiff. 5) Wash off your mixing tools. Use a hose on the strongest setting to spray your tools and blast away any remaining concrete before it sets.
Which cement is best for concrete slab construction?
PPC contains fly ash and hence offers greater strength to the slab and hence eco-friendly
