Hello everyone, I'm Director Huang to see manufacturing!Today I'm going to give you an in-depth analysis of cement, the magic material in the field of construction!Cement evolved from stone, wood, and earth, and it plays a vital role in the field of construction. Let's take a look at the development process of cement and its magic!
In ancient times, people used stone, wood, and earth to build houses. Although lime mortar has been used in construction, it cannot meet the needs of construction due to its limited strength. So, in the sixth century AD, the clever Chinese invented a new building material called glutinous rice lime mortar. This material is made by mixing glutinous rice soup with lime mortar, which has higher strength and is even capable of building durable buildings such as Changcheng and Ming city walls.
With the continuous advancement of construction technology, the demand and requirements for cement are also getting higher and higher. Today, more than 100 different types of cement have been developed to meet different construction needs and provide strong support for the development of the construction industry.
Cement, as we used to call it as "ash" as a child, is a powdery material whose main components include limestone, clay and iron ore fines. When mixed with water, it becomes a slurry that hardens to become a strong building material. Modernly built bridges, houses, roads, etc., are inseparable from the important contribution of cement.
There are many different types of cement like Portland cement, aluminate cement, sulfoaluminate cement, iron-aluminate cement, fluoroaluminate cement, and phosphate cement. Each type of cement has different properties and uses.
When cement is added with water, it forms a slurry that can be processed at will, and after a period of solidification and hardening, it becomes a strong building material. This process of solidification and hardening is very complex. The substances in the cement react with water to form fine crystals, which bond together to form a solidified structure. Over time, the substances in the cement continue to react with the water, and the fibers become more and more connected, eventually forming a solid whole.
The solidification rate and strength of cement are affected by many factors, such as temperature, water addition, ratio, and different types of admixtures.
Cement, a magical material that evolved from stone, wood, and earth, has contributed greatly to the development of the construction industry. It makes our cities stronger and more beautiful, providing a safe and comfortable environment for our lives.
