Chema Block is a lightweight EPS void former coated with polymeric concrete, engineered to reduce slab weight, minimize material consumption, and simplify installation for ribbed and wide-span slab systems.

Properties

• Reduces concrete consumption by up to 35%.
• Reduces steel reinforcement weight by up to 30%.
• Cuts total building cost by up to 40%.
• Lightweight and easy to install.
• Strong bonding with concrete slabs.
• Enhances structural efficiency of ribbed slabs and wide spans.

Areas of Use

• Ribbed slab systems as an alternative to hollow blocks.
• Wide-span structural slabs requiring weight reduction.
• Bridge decks, tunnel ceilings, and lightweight elevated slabs.
• Interior slab uplift applications.

Installation Method
• Spans 5–7 m

One-way Chema Blocks placed in continuous rows.
Ribs spacing: 40–60 cm.
Rib width: 10–12 cm.

• Spans 8–12 m

Two-way Chema Blocks placed with ribs in both directions.
Ribs spacing: 60–100 cm.
Rib width: 12–15 cm.

Notes

• Electrical conduits should pass between ribs.
• Rebar must be lifted above blocks using rebar spacers.
• Slab and finishing layers should be water-cured for at least 7 days to enhance concrete strength.

Technical Data

Safety Precautions

• Chema Block is breakable and should be handled carefully.
• Keep away from sparks, fire, and heat sources.
• Avoid contact with strong oxidizing agents or aromatic solvents.
• Do not stack blocks improperly or under excessive weight.

Storage & Shelf Life

• Store in a dry, shaded, ventilated area.
• Avoid prolonged exposure to sunlight or high temperatures.
• Maintain flat, clean storage surfaces.
• Long shelf life when properly stored.
