Fine aggregate refers sand and crushed stone or any particulate material that is small in size but suitable for construction. It is used as a foundation material or underlayment to paving projects.

Concrete is the process of constructing a concrete structure. Mixing cement, aggregate and water creates a strong material that can then be used to construct walls, floors, or other structures. Concrete can be used to create durable structures that last years.

Frequently Asked Questions

If you use too much cement in concrete, it can adversely affect the strength and durability of the final product. The amount of cement in a concrete mix is typically expressed as a "cement to sand ratio" or a "cement to aggregates ratio". A higher-than-normal cement ratio means that there will be more cement paste surrounding the individual aggregate particles, which can make the concrete weaker and more susceptible to cracking. Conversely, using too little cement will also lead to substandard concrete; in this case, the mixture will be more likely to experience shrinkage cracking as it dries. It's therefore important to get your proportions right when making concrete, in order to ensure a high-quality final product.

No, you don't need rebar for a 4 inch slab. However, if you're planning on putting anything heavy on the slab or if it will be subject to high stress, then adding rebar is a good idea. Reinforcing the slab with rebar increases its strength and durability, making it less likely to crack under pressure. 

If you're not sure whether or not your project needs rebar, it's always best to consult with a professional engineer or contractor. They can help you assess the risks and decide whether reinforcing the slab is necessary.

Adding cement to concrete does indeed make it stronger. cement is a hydraulic binder, meaning it binds well with water. This makes it ideal for use in concrete, as the water helps to activate the chemical process that makes concrete harden. The more cement you add, the stronger your concrete will be. 

That being said, there is such a thing as too much cement. Too much cement can actually weaken concrete, as it causes the paste to become too fluid and accelerates the hydration process, leading to cracks and shrinkage. So while adding cement will make your concrete stronger, be sure not to add too much or you could do more harm than good!
