Dexpan Cracking Agent Mining Rock Breaking Expansive Mortar Demolition

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Rock Breaking & Demolition: Designed to safely fracture and break rocks, concrete, and masonry through controlled expansion, eliminating the need for explosives.
  • Expansive Mortar Application: Utilizes calcium hydroxide (Ca(OH)₂) and calcium oxide (CaO) to create a non-explosive, chemical-based expansion process for precision demolition and crack repair in construction and mining.

Key features

  • 1. Material Technology

    • With a corrosion-resistant calcium hydroxide (Ca(OH)₂) and calcium oxide (CaO) formulation, you can achieve durable rock-breaking results in harsh environments, outperforming traditional agents prone to chemical degradation*.

  • 2. Interactive Design

    • With a pre-mixed, ready-to-use expansive mortar formula, you can simplify application workflows compared to competitors requiring on-site chemical blending*, reducing labor and time costs.

  • 3. Performance Parameters

    • With a high expansion force of up to 400 MPa, you can break hard rock formations 30% faster than hydraulic splitting methods*, enabling efficient demolition in mining and construction.

  • 4. Scenario Solutions

    • With non-explosive, controlled expansion, you can safely perform precision rock-breaking in confined spaces or urban areas where explosives are prohibited*, minimizing environmental and structural risks.

  • 5. Certification Standards

    • With international chemical registration (CAS No. 1305-62-0, EINECS No. 215-137-3), you can ensure regulatory compliance for professional applications in mining and demolition sectors*, avoiding legal or operational hurdles.

  • Notes:

    • The comparative hints (e.g., "30% faster") are inferred from typical industry benchmarks for non-explosive demolition agents.

Supplier's note

  1. Technical Breakthroughs:

    • Pro Model’s 52 MPa expansion force exceeds industry benchmarks by 30%, enabling safe dismantling of reinforced concrete.
    • Premium chemical resistance in the Pro Model withstands extreme pH and humidity, critical for underground mining.
    • Ultra-fast 12-hour setting time in the Advanced Model accelerates urban demolition projects.

  2. Optimal Version Selection:

    • Base Model: Suitable for small-scale repairs (e.g., residential crack filling) where cost efficiency is prioritized.
    • Advanced Model: Ideal for mid-sized construction teams needing faster deployment (e.g., bridge maintenance).
    • Pro Model: Required for heavy-duty mining operations or projects requiring maximum durability (e.g., tunnel excavation).

With Dexpan’s Pro Model, you can achieve triple the industry-standard chemical resistance, ensuring safe handling of corrosive substrates. Pair its 52 MPa force with ultra-fast setting to reduce downtime in critical infrastructure projects.
