The use of cement is a fundamental aspect in construction, as it serves as the bonding material that holds together concrete structures. In English, cement is referred to as "cement." Here is a brief article on the subject:
The Importance of Cement in Construction
Cement is an essential ingredient in the production of concrete, which is the most widely used construction material in the world. Its primary role is to bind sand, aggregates, and water together to form a strong, durable material suitable for a variety of construction projects.
In English, cement is simply called "cement." This inorganic compound is typically gray in color and is produced by heating a mixture of calcium carbonate (limestone) and silicon dioxide (sand) to a high temperature. The resulting product, called clinker, is then finely ground with gypsum to form the final cement powder.
The process of cement production is both energyintensive and environmentally impactful. However, with advancements in technology and sustainable practices, the industry is working towards reducing its carbon footprint and environmental impact.
When working with cement, it is crucial to understand the different types available, such as Portland cement, which is the most common, and other specialty cements for specific applications. The quality of cement can significantly affect the performance of concrete, making it a critical factor in the construction process.
In conclusion, cement, a key component of concrete, plays a vital role in modern construction. Its English name, "cement," reflects its universal use in the industry.

问答详细解答
1. What is cement?
Cement is a binding, hydraulic material used in construction. It hardens and gains strength over time when mixed with water, allowing it to bind other materials together to form concrete.
2. How is cement made?
Cement is made by heating a mixture of limestone (calcium carbonate) and clay (silica and alumina) to a high temperature (around 1500掳C), which forms clinker. This clinker is then ground with gypsum to produce cement powder.
3. What is the primary use of cement?
The primary use of cement is to make concrete, which is used in construction for foundations, walls, floors, and roofs, among other applications.
4. What is the difference between cement and concrete?
Cement is a powder that, when mixed with water, hardens to form concrete. Concrete is a composite material made primarily of aggregates (sand and gravel) and cement.
5. What are the types of cement?
Types include Portland cement, slag cement, fly ash cement, and specialty cements such as oilwell cement and rapidhardening cement.
6. What is Portland cement?
Portland cement is the most common type of cement used in construction, known for its strength and versatility. It is made primarily from limestone and clay.
7. How does cement contribute to the environment?
Cement production is energyintensive and produces greenhouse gases. However, advancements in technology and sustainable practices are reducing its environmental impact.
8. What is the role of gypsum in cement?
Gypsum is added to control the rate at which cement sets and hardens. It also contributes to the strength of the final product.
9. Why is cement called "cement"?
The word "cement" comes from the Latin word "caementum," meaning "coating" or "mending," reflecting its historical use in mending or filling gaps.
10. How does cement harden and set?
Cement hardens and sets through a chemical reaction called hydration, where water reacts with the cement's chemical compounds to form a crystalline structure, gradually increasing in strength over time.
