In 1824 Joseph Aspdin, a British stonemason, obtained a patent for a cement he produced in his kitchen. The inventor heated a mixture of finely ground limestone and clay on his kitchen stove and ground the mixture together into a powder to create a hydraulic cement-one that hardens with the addition of water. He named the product Portland cement because it resembled a stone quarried on the Isle of Portland, off the British coast. With this invention, Aspdin laid the foundation for today's Portland cement industry.

How cement get hard?
Cement hardens through a chemical process called hydration, where water reacts with the compounds in the cement to form crystals. This process creates a strong and durable bond between the cement particles, resulting in a solid and hardened structure. Factors such as water-to-cement ratio, temperature, and curing time can affect the strength and durability of the hardened cement.
Why does cement solidify?
Cement solidifies through a chemical process called hydration, where water reacts with the compounds in the cement mixture to form a solid structure. This process creates strong bonds between the cement particles, resulting in a solidified mass that hardens over time.
What is basic ingredient for making cement?
The basic ingredient for making cement is limestone. This is crushed and mixed with clay or shale and heated to high temperatures in a kiln to create a substance called clinker, which is then ground into a fine powder to produce cement.
What is the formula of making cement?
Cement is made by combining limestone, clay, sand, and other raw materials in specific proportions and then heating the mixture in a kiln to high temperatures. The resulting product, called clinker, is then ground into a fine powder to create cement.
Why does cement bond?
Cement bonds because of a chemical process called hydration, where water reacts with the compounds in cement to produce a strong, durable paste that binds the particles of sand and gravel together. This paste hardens over time to form a solid structure.
What is the difference between cement paint and cement based paint?
Acrylic or epoxy based paint for cement surfaces is called cement paint.Cement that includes acrylic or epoxy to coat surfaces is called cement based paint.
What animals eat cement?
I don't think any animals eat cement, but if they did then it would harden inside of them and they would die. Any animal who eats cement is called a cement eater therefore he eats cement and if they eat iit then they will die...... socement eaters are what eat cement

Why use cement for a house slab and not concrete?
Residential slabs are made of concrete, often called cement although it contains cement, sand, and aggregate (usually rocks of pebble size).

What are the 3 different types of cement bind together sand in sandstone?
Silica also called quartz cement, Calcite Cement, Iron Oxides also called hematite cement that bind sand together in sandstone. Sandstone also has other cementing agents that occur in less common forms. These cementing agents include pyrite, barite and gypsum.
