It’s valued for its low clay content, which can make the concrete stronger and more durable. The key differences among these types of sand lie in their source, grain size, and shape. Concrete sand is preferred for its coarseness and ability to bind well, which is vital for the structural integrity of concrete.

· The fundamental difference to understand is that cement is an ingredient in concrete, and it can contain “cement additives.”. Concrete contains cement, sand, aggregate, and water, and it may contain various “concrete admixtures” that enhance its properties during mixing. Here we’ll further break down cement additives and concrete

Another way to strengthen concrete is to incorporate steel into the mix. This is not done using fine particles. Instead, the concrete is poured over steel bars or cables that are woven into a mesh. The mesh is completely encapsulated into the concrete. The steel adds reinforcement to the concrete, providing extra help in handling tension.

Luckily, there are concrete additives that can be used to improve a concrete mixture’s properties, whether it needs to be stronger, more durable, or easier to use. If you’re planning on pouring concrete soon, read on for the lowdown on what concrete additives are and how to determine which ones you’ll need for your project.

· The strength of concrete is measured in psi or pounds per square inch. Typically a footing should be at least 3500 psi. To make the mix, add 1 part Portland cement, 2 parts sand and 4 parts stone aggregate by volume. Add in 3 quarts water per 80 pounds of dry concrete. Aggregate should be between 1/2 – 1 inch in size.

· Concrete additives are chemical or mineral compounds added to concrete mixes during mixing to alter or enhance certain properties of the concrete. These additives work by interacting with the cementitious materials in the concrete mixture, influencing the hydration process and modifying the microstructure of the hardened concrete.
