Frequently Asked Questions
Find answers about Cement, Concrete, Construction Equipment, Concrete Mixers, Building Materials, Suppliers and the CementMixer Marketplace.
We use the terms Cement and Concrete interchangeably in some product labels because terminology varies around the world. In the United States, "Concrete" is generally used for the finished product, while in many other countries "Cement" is commonly used in everyday conversation.
Where technical accuracy matters, we use the correct terminology such as Portland Cement, Mortar Mixers, and other specialized construction products.
CementMixer.com is a global construction marketplace connecting buyers, suppliers, manufacturers, contractors, and equipment dealers through one trusted platform.

General Questions
1. What is Cement?
Cement is a binding material used in construction that combines with water and aggregates to produce concrete used in buildings, roads, bridges and infrastructure.
2. What are the main types of Cement?
The most common types include:
- Portland Cement
- White Cement
- Slag Cement
- Pozzolan Cement
- Rapid Hardening Cement
- Low Heat Cement
3. How is Cement manufactured?
Cement is produced by heating limestone and other minerals in a rotary kiln to form clinker, which is then finely ground with gypsum.
4. What is the difference between Cement and Concrete?
Cement is one ingredient. Concrete is the finished construction material made from cement, sand, aggregates and water.
5. Why are admixtures used?
Admixtures improve workability, strength, setting time, durability, and weather resistance.
6. How should Cement be stored?
Store cement in a dry place, off the ground, protected from moisture, and away from rain.
7. What is the ideal Water-Cement Ratio?
Generally between 0.40 and 0.60 depending on the project requirements.
8. Why is curing important?
Proper curing helps concrete achieve maximum strength, durability, and crack resistance.
9. How is Concrete mixed?
- Drum Mixers
- Pan Mixers
- Twin Shaft Mixers
- Transit Mixers
- Ready Mix Trucks
10. What safety equipment should be used?
- Safety Glasses
- Dust Mask
- Gloves
- Safety Shoes
- Hard Hat

For large commercial projects, always consult your structural engineer or quantity surveyor.
Construction Industry & Standards
21. What is a Building Code?
Building codes establish the minimum safety, structural, electrical, plumbing, fire protection, and occupancy requirements for construction projects to ensure public safety and compliance.
22. What is Structural Engineering?
Structural engineering focuses on designing and analyzing buildings, bridges, foundations, columns, beams, and other structural elements to safely support loads and withstand environmental forces.
23. What does MEP stand for?
MEP stands for Mechanical, Electrical, and Plumbing. These systems are essential for heating, cooling, lighting, ventilation, water supply, drainage, and fire protection within buildings.
24. What is a Construction Bid or Tender?
A construction tender is a formal proposal submitted by a contractor or supplier to complete a project or supply materials at a specified price and within a defined scope of work.
25. What is the difference between a General Contractor and a Subcontractor?
A General Contractor manages the overall construction project, while Subcontractors perform specialized work such as electrical, plumbing, roofing, HVAC, or finishing.
26. What is the role of an Architect?
Architects design buildings, prepare construction drawings, coordinate with engineers, and ensure projects meet functional, aesthetic, and regulatory requirements.
27. What is a Building Envelope?
The building envelope includes the roof, walls, windows, doors, and foundation that separate the building's interior from the outside environment while improving energy efficiency and weather protection.
28. What are Green Buildings?
Green buildings are designed to reduce environmental impact by improving energy efficiency, water conservation, indoor air quality, and the use of sustainable construction materials.
29. What is LEED Certification?
LEED (Leadership in Energy and Environmental Design) is an internationally recognized certification system for environmentally responsible and sustainable building projects.
30. What does a Construction Project Manager do?
Project managers oversee planning, budgeting, scheduling, procurement, quality control, safety, communication, and successful delivery of construction projects.
31. What is Precast Concrete?
Precast concrete products are manufactured in a controlled production facility and transported to the project site for installation. Common examples include concrete pipes, drainage systems, retaining walls, barriers, septic tanks, culverts, and stormwater products.
