Cement Mat Replaces Traditional Materials - Superior Technology Solves Water Conservancy Challenges
During heavy rain seasons, muddy water carrying detritus frequently appears in various waterways, which causes blockages, overflows and even the destruction of structures. Traditional waterways construction need longer construction period, higher costs, and requires frequent maintenance. It is difficult to deal with disasters. In contrast, Cement Mat, as a new type of geosynthetics , which features faster construction, excellent performance and extremely low maintenance costs. Its various indicators all meet the needs of current water conservancy projects.
Cement Mat Overview
Cement Mat is a pre-mixed, flexibly applicable, pool-type engineering material. It is also called "Geosynthetic Cementitious Composite Mats (GCCM)", which is used as an alternative to conventional concrete for its advanced. The construction process is divided into two major steps:
Step 1: Pre-Construction Preparation
Ensure the waterways has a reasonable slope gradient, enabling water to flow from top to bottom.
Clear the site, set construction lines, and recalculate drainage slope gradients.This is essential part for fix cement mat on the slope.Then remove humus soil, hard rocks and unsuitable subsoil. Reinforce foundation, soil replacement and compaction based on substrates or slopes.
Follow the drawing, choose either a longitudinal or transverse belt layout pattern of cement mat. At the seams of each piece of cement mat, maintain an 10cm overlap and using U-shaped staples or stainless steel buckles to fix down. At last, cover the edges with soil.
Step 2: Hydration hardening
After foundational work acceptance, start clean water irrigation:
Use a water volume of approximately 9 kg/m2(as base thickness of 10mm). Pour water evenly from the edges towards the center at a flow rate of 400ml/min.
Continue watering until the color of the cement mat turns darker noticeably. Full hardening occurs in about 24 hours after contacting water.
Precautions:
- Do not use high-pressure water jets.
- Avoid stepping on cement mat after watering.
- When temperatures drop below 5°C, insulation measure is must.
- When average temperatures exceed 30°C, cover with geotextile to maintain moisture retention.
- Full hardening has time requirement: within 2 hours after water contact, cutting is still possible. But after 24 hours, the shape is fixed and stable.
"The Perfect Answer Under the Concept of Reducing Costs and Increasing Efficiency in Water Conservancy Engineering"
Compared with traditional waterways construction involves building stone dams or using cast-in-place concrete, requiring large concrete mixing equipment and experienced construction personnel. Our new-type Cement Mat can be applied to various terrains with extremely high construction efficiency. It meets strength requirements while reducing the overall construction cost. Besides, its material usage, resource consumption and carbon emissions are much lower. Nowadays cement mat embodies the development direction of energy conservation, emission reduction and environmental protection.
