Plain cement concrete (PCC) is simply concrete by definition. It is cement + water + fine aggregates + coarse aggregates. It is the ordinary concrete without any kind of reinforcement.
DESCRIPTION: CEMIX NO STEEL is a construction grade concrete used in civil, commercial, industrial and residential applications. It is a mixture of sands, aggregates, Portland cement, admixtures and reinforcing fibres.
Do All Concrete Projects Need Reinforcement? No, they do not. Larger projects or slabs may need steel reinforcement to provide support or extra strength. Wired mesh can also help resist cracking.
There are three different types of concrete: Portland cement, aggregate, and water. Portland cement is the main ingredient in concrete.
Without steel reinforcement, the tensile strength of the concrete elements is very limited.

Rebar is not necessary for every concrete project. The general rule of thumb is that if you are pouring concrete that is more than 5 inches in depth, you are probably going to want to add in some rebar to help reinforce the entire structure.
3. Plain or Ordinary Concrete. This is another concrete that uses the common mix design of 1:2:4 with its components of cement, sand and aggregates. You can employ it to make pavement or buildings where there is not a high demand for tensile strength.
Bottom line: Cement is a powdered ingredient used to make concrete. Concrete is the material used to make sidewalks, driveways and buildings. Sakrete makes a number of different concrete formulations in varying strengths and set times to meet the needs of different job requirements.
Yet, whilst concrete has substantial compressive strength (usually up to 4,000 psi in domestic and standard commercial buildings), it is relatively weak in tensile strength, meaning that it can break or crack under shear forces. To mitigate against tensile weakness, concrete is routinely reinforced with steel.
Corrosion of steel in reinforced concrete structures has cost a significant amount of resources globally over the past few decades. Glass fiber reinforcement polymer (GFRP) bars present a feasible and cost-effective solution to the problem of steel corrosion.
Concrete roadways, platforms, and structures typically require some type of reinforcement to help reduce cracking and prevent architectural failure. Most often, rebar (steel bars) are embedded into the concrete before it hardens. However, galvanized panels of welded wire mesh can be used as an alternative to rebar.
Concrete without cement is possible with the use of fly ash as an alternate for cement. It matches both the chemical and physical properties of cement. Thus it has the ability to replace cement completely. The word “concrete” defines as the bonding between aggregates, cement and water.
Zero Cement Concrete is an improved version of Geo-polymer Concrete wherein the thermal activation of the binding materials such as Fly Ash and Ground Granulated Blast Furnace Slag (GGBS) is done with the help of alkaline solution namely Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3).
Not only are precast concrete products already reinforced with steel rebar, but the controlled curing process also ensures that the concrete will set correctly under ideal conditions for maximized strength.
It's worth noting that you can't use cement alone. You will need to mix the other materials with the cement (in the right ratio) to make your concrete or mortar mix. Knowing which material will be best for your project, at the correct ratio, is crucial to making your project a success.
Working With Ready-Mix Concrete
And, if you mix it yourself, it's the cheapest way to make your slab. For most do-it-yourselfers, the best material for building a concrete slab is a ready-mix, crack-resistant concrete product. The wet mix is poured into a prepared wood form, then left to cure.
Let's start with the basics: concrete is significantly stronger than cement. Cement is a durable material in its own right, but it simply does not compare to concrete. That's why cement is usually used for smaller, more decorative projects.
PCC stands for Plain Cement Concrete. PCC is a combination of cement, sand-like fine aggregate, and coarse aggregate. Another name for it is blinding concrete or cement concrete (CC).
Modern concrete is typically made with portland cement, a mixture of silica sand, limestone, clay, chalk and other ingredients melted together at blistering temperatures.
PLASTIC. The first state of concrete is known as the plastic state, which refers to the concrete when it's wet. Concrete is made of aggregate, water, and cement, and all these ingredients are mixed together to create a building material that allows you to maneuver it into position.
Glass fiber reinforced polymer (GFRP) Rebar
It is 75% lighter than steel, does not corrode, and is quite durable. Its high elasticity reduces the number of applications it can be used it, but in the applications it has been tested in its results have been promising.
GFRP Bar is a composite material of longitudinal fibers, Polyesters resins, and matrix material. It is the best alternative to Conventional Steel Rebar.
The hemp rebar could be used to support concrete structures in the same way as steel and other rebars are today, but with a reduced environmental impact due to both its material makeup and its lifespan.
