Cement

Cement is a fine grey powder commonly used in construction for making mortar, render, plaster, and concrete. When cement, sand, and water mix, they produce a strong binding paste. This mixture forms a strong binding paste that sets and hardens to lock materials together.

What Is Cement Mix?

Cement mix can refer to:

• Cement paste – Made with just cement and water. The basic binder used in all cement mixes.
• Mortar – This is a mix of cement, sand, and water. It is used for pointing, bricklaying, bedding blocks, patching, and general repairs.
• Plaster/render – This is a mix of cement, fine sand, and water. It is a smoother mix for coating walls and finishing surfaces.
• Concrete – This is a mix of cement, sand, gravel, and water. A strong structural mix for floors, bases, and heavy-duty work.

The strength and setting time of any mix depend on the type of cement used and water-to-cement ratio

What Is Cement Bag Used For?

The 25kg cement bag is the standard unit most builders buy. It is designed for easy handling and accurate mixing on-site.

One bag offers a fixed amount of binder, suitable for on-site jobs, such as:

• Patching
• Bedding blocks
• Making small batches of concrete
• Plastering walls
• Preparing floor screeds

Types Of Premium Cement

There are various cement grades, including fast-set, high-early strength, blended cements. The standard bag available at Insulation Wholesale is a Portland-limestone variety with a 42.5N compressive strength.

It is commonly used for plaster, mortar, and screeds used alongside insulation boards and plasterboard finishes. It offers a reliable, even finish that works with most thermal and acoustic insulation installations.

Benefits Of Cement Bags

Here are the benefits of buying cement bags:

• Portable and consistent: each bag provides the same mix ratio to deliver reliable results.
• Versatile: for mortar, screed, render, and plaster.
• Measured strength: labelled strength (e.g. 42.5N) matches the material to the job.

What cement is made of

Cement is mostly clinker (the product of burning limestone and clay at high temperature), ground with a little gypsum to control setting. Chemically it contains calcium silicates, aluminates, and ferrites that hydrate into the hard binding phases. That’s why it is called a hydraulic binder – it hardens by reacting with water.

Can cement be painted?

Yes, you can – but the cement has to be well cured. Use paints formulated for masonry.

1. Clean the surface.
2. Repair cracks, if any.
3. Apply a masonry primer or bonding agent (optional).
4. Paint with a suitable masonry or concrete paint.

For durable results on floors or external areas, choose a paint specified for concrete use.
