Engineered to exacting industry standards, Deslauriers concrete testing cylinders deliver uncompromising accuracy for compressive strength tests, slump verification, and quality assurance programs. Crafted from rugged, non-absorbent bio-degradable polypropylene, these laboratory-grade cylinders resist cracking, warping, and chemical degradation—ensuring consistent results across repeated uses in harsh jobsite or lab environments. The seamless, leak-proof construction and precisely molded dimensions (standard 4"x8" or 6"x12") guarantee full compliance with **ASTM C31/C39** and **AASHTO T 23** specifications, while the reinforced base and flanged top simplify filling, handling, and transport. Ideal for DOT projects, ready-mix plants, and construction firms, our cylinders feature easy-stack design for efficient storage and durable plastic caps (sold separately) to protect samples. Trust Deslauriers’ legacy of precision: order certified cylinders that eliminate testing variables and safeguard your compliance data.
