Technical Innovative Solutions

Meeting Construction Needs of the Present Without Compromising Those of the Future

Staying true to our legacy of pioneering many industry firsts in Sri Lanka, we continue to introduce and integrate sustainable solutions across the local construction industry. We have focused on a number of areas to drive sustainable development, augmenting sustainability performance in our products & solutions, processes and the structures that bear the INSEE name.

Mix Design optimization and solutions development

When it comes to optimizing concrete mixes, INSEE Cement offers comprehensive solutions to help clients meet all structural, performance and economical requirements of a construction project. We use simulations, advanced technologies, testing equipment and our years of accumulated expertise to evaluate numerous parameters such as water-cement ratio, cement type, percentage of cement, aggregate grading and percentage, and more to obtain the best balance between performance and cost optimization of the mix design for our clients.

We offer:

  • Pre-Project Mix Design Evaluations – During planning stages of the project. The INSEE team consults the client, contractors and site engineers on the mix requirement, evaluating requested concrete mixes and delivering necessary results for decision making.
  • New Mix Design Introduction & Recommendations – Due to the mutually beneficial nature of the relationships we have nurtured with our clients over the years, we recommend our own findings and research results of new and improved mix designs to our clients during initial stages of projects, where significant changes and impact can be made on the required outcome. In order to provide accurate recommendations, we:
    • Assess rheological parameters of fresh concrete
    • Introduce new durability testing tools and methods
    • Simulate the pumpability of concrete mixes
    • Generate test results and statistics for aggregates of the mix design
    • Assess durability, workability and strength gaining aspects of superior blended cements
  • Mix Design Performance & Cost Optimization – Followings simulations, thorough testing and evaluation of results, we help clients determine the best proportions of the constituents of the concrete mix and ensure the final optimized mix design delivers the desired properties of fresh / hardened concrete, cost-effectively.
  • Mass Pouring Thermal Simulation – INSEE Cement offers clients advanced Thermal Modeling with INSEE ConTemp™ – a simulation software that creates thermal mockups to determine the Heat of Hydration of the mix for mass pouring projects before the actual mixing.The level of detailed simulation earlier in the design and planning process of a construction project greatly benefits clients by reducing running / building costs and enabling critical decision-making.

Application needs-based Products and Solutions

Today’s rapid pace of construction and infrastructure development has led to innovative new concrete solutions that are heavily application needs based. From time-sensitivities to rapid drying, from thermal modeling to special surface treatments, varying client requirements have resulted in the INSEE team developing customer-led, application needs-based solutions:

  • Pervious Concrete – Sustainable solution for pavements and roads
  • High Early Strength Concrete – Reduces project cycle time and overhead cost
  • High Performance Concrete – Displays enhanced physical properties such as rapid strength gain, high durability, etc.
  • High Durable Concrete – Improves operational cost efficiency by reducing maintenance cost and assuring longer life time in aggressive environments
  • Pumped Concrete – Fluid with high workability, ideal for high-rise constructions and large pouring

Innovative solutions for scarcity of raw materials through beneficiation and valorization

With the exhaustion of natural resources and the repercussions the world currently faces therein, INSEE Cement is leading the local construction industry to proactively discover and implement innovative ways to sustainably re-use, conserve and substitute resources in construction practices. Our approach to resource conservation includes:

  • Material/ Aggregate Testing and Recommendation – To promote sustainable resource utilization and re-use
  • Substitution
    • Usage of M-Sand with improved rheological parameters
    • Usage of sea sand as a solution to reduce overall project cost and lifecycle
    • Usage of red sand as a fine aggregate
    • Experiment with LG LS as a lightweight aggregate
