Just look around to see all the uses of concrete in our daily lives! Concrete made of Portland Cement is a subject to all types of degradation starting with Carbonation as soon as it comes in contact with the atmosphere.
The thing most people overlook is that when concrete is placed, the water in the mix in addition to hydrating the concrete, is trying to evaporate out of the matrix to the atmosphere. In doing so, Bleed water is expelled to a surface. The channels this water travels through is called a gel-pore or capillary system. Once the water is gone -- this capillary system remains open allowing contaminates to enter the concrete. Concrete is a Big Sponge that breaths for years after it is poured.
A sealer to protect it is Vital to Longevity. Choose a sealer wisely. Surface membrane type sealers don't last! Stay away from a sealer that cautions Do Not expose to metals or glass. That is a Sodium Silicate based product that is gone in less than a year! Any sealer that allows for another coating at some future date?? Doesn't this beg the question of "What happened to the first application"?
Get a penetrating sealer to seal the gel-pore system, that doesn't form a film membrane and has a 15 year warranty for water proofing.
What else can I help you with?
Are portland cement rocks sand and water a compound?
Yes, Portland cement rocks, sand, and water are indeed a compound.
What is the specific gravity of portland cement?
According to ASTM C188 the specific gravity of Portland cement is roughly 3.15According to ASTM C188, the specific gravity of portland cement (without voids between particles) is about 3.15. In other words, portland cement is about 3.15 times heavier than water.
Why Portland cement is called hydraulic cement?
Portland Cement is classified as "hydraulic" cement because it cures or solidifies due to its chemical exchange with water, stemming from the building material's ability capability to set under water. In the well industry Portland Cement can be placed or pumped into voids at thousands of feet in depth. As long as the mixture is released or pumped without significant breakdown of the mixture due to water flow the cement will cure just as well we see during ground level applications.
How can you make portland cement as quick setting and water resistance cement?
Please note that a key correction in terminology is essential before your question can be answered: use the word "concrete" instead of "cement." The answer is to modify your mix (i.e. Portland cement, sand, gravel, and water) by using hydraulic cement to repace part of the Portland cement. The higher the amount of hydraulic cement you add, the quicker the setting time and the impermeability. However, hydraulic cement sets so quickly that you have limit the amount of total mix so as to be able to pour it and form it before it sets.
Why use kerosene in the test specific gravity of cement?
Kerosene, a petroleum product will not interact chemically with Portland cement - water will.
What is the waterproof protein in the skin?
If by waterproof you mean water-repellent, then yes.
What is waterproof cement?
Waterproof cement is a type of cement that is formulated to resist water penetration and moisture ingress. It is commonly used in projects where water resistance is important, such as basements, swimming pools, and other water-retaining structures. Waterproof cement typically contains additives that enhance its resistance to water and help prevent water damage.
Are portland cement rocks sand and water a compound?
Yes, Portland cement rocks, sand, and water are indeed a compound.
Is cement waterproof?
Cement itself is not waterproof, but when mixed with water and other materials to make concrete, it can be made waterproof by adding additives or sealants.
What is the specific gravity of portland cement?

What are waterproof and water-repellant fabrics?
Waterproof and water-repellent fabrics materials treated with various substances so as to make them impervious to water. Some examples are: Gore-tex Vinyl Fluoropolymers
Difference between water repellency and waterproof?
Something that is water repellent will protect you from a light rain, but will eventually allow water to seep through and get you wet. Waterproof means that it will keep water from seeping through even in a heavy rain. Most garments are made to be repellent to allow our perspiration to evaporate and tents are usually made to be waterproof, especially the floors.

What is specific gravity of portland pozzolona cement?
The specific gravity of portland pozzolana cement is 3.15.The specific gravity test can be done on cement using the bottle method.In this method instead of water kerosene is used to test the specific gravity of cement.
Is Goretex really waterproof?
Gore-Tex is more water repellent than waterproof. Some owners of Gore-Tex complain that the repellent layer wears off over time.
What mineral is used to make stucco?
Lime, sand , sometimes Portland cement, and water.
