Frequently Asked Questions (FAQ) Concrete Cylinder Mold 100×200mm 

Q1. What standard does this concrete cylinder mold 100×200 mm follow?

This mold follows ASTM C31 (Standard Practice for Making and Curing Concrete Test Specimens in the Field), BS 1881 Part 110, and AASHTO T 23. These are the most widely accepted standards in Bangladesh for concrete quality-control testing. Concrete Cylinder Mold 100×200mm

Q2. Can I reuse the mold multiple times?

Yes. The mold uses heavy-gauge steel construction for multiple reuses. You clean the interior after each use with a mold-release agent, inspect the clamp and base plate for damage, and the mold is ready for the next casting .

Q3. How do I assemble the mold before casting?

First, place the base plate flat on a rigid surface. Next, position the two-piece cylindrical body on top of the base plate. Then, tighten the seam clamp firmly to close the joint and prevent paste leakage. Finally, apply a thin coat of mold-release oil to the interior before you pour the concrete Concrete Cylinder Mold 100×200mm .

Q4. What is the specimen volume this mold produces?

The mold produces a cylinder with a volume of approximately 1,571 cm³ (100 mm diameter × 200 mm height). This volume is the standard reference size for concrete compressive strength testing per ASTM C39.

Q5. Does AsTz BD offer bulk pricing for labs or contractors?

Yes. AsTz BD provides bulk-order discounts for purchases of 10 or more molds. Contact us through astzbd.com or by phone to receive a bulk quotation with delivery terms.

Q6. How long does delivery take in Bangladesh?

AsTz BD delivers to Dhaka within 1–2 business days and to other major divisions including Chittagong, Sylhet, Rajshahi, Khulna, and Barishal within 2–4 business days, depending on courier availability.

Q7. Is this mold compatible with a compression testing machine?

The mold itself is for casting only. After curing, you remove the hardened specimen from the mold and place the cylinder directly into a standard compression testing machine for the ASTM C39 compressive strength test.

Q8. What payment methods does AsTz BD accept?

Astz BD accepts bKash, Nagad, bank transfer, and cash on delivery (COD) for eligible locations. You can place your order through astzbd.com or contact the sales team directly for institutional purchase orders Concrete Cylinder Mold 100×200mm.
