Key Responsibilities

1.

Client Requirement

Assessment

- Attend technical meetings with client technical leads and understand the client’s concrete performance requirements.

- Collect details of cement, SCMs, aggregates, water, concrete mix design, required slump/flow, retention time, setting time, and strength targets.

- Understand requirements for RMC, precast, infrastructure, high-strength, and special concrete applications.

2.

Admixture

Development

- Develop and modify PCE-based concrete admixtures according to client requirements.

- Select suitable PCE grades, slump-retention polymers, accelerators, retarders, defoamers, and other performance additives.

- Optimize admixture dosage and formulation for water reduction, slump/flow retention, early strength, high strength, pumpability, and setting-time control.

- Balance technical performance with commercial product cost.

3.

Laboratory

Trials

- Conduct cement compatibility, mortar, and concrete trials before customer-site trials.

- Evaluate initial slump/flow and retention at required intervals such as 30, 45, 60, 90, and 120 minutes.

- Monitor water reduction, setting behaviour, air content, density, segregation, and bleeding.

- Cast and test cubes for early-age and final compressive strength.





- Maintain complete laboratory trial records and technical reports.

4. In office Trials & Product Finalization

- Visit client RMC plants, precast plants, and project sites for concrete trials.

- Perform trials using actual client raw materials and mix designs.

- Adjust admixture formulation and dosage based on site performance.

- Finalize the admixture design at the customer site after achieving the required performance.

- Provide technical support during initial commercial supply and implementation.

5. Troubleshooting

- Investigate slump loss, delayed or rapid setting, segregation, bleeding, low early strength, low final strength, and poor pumpability.

- Identify whether issues originate from cement, SCMs, aggregates, water, mix design, production conditions, or admixture compatibility.

- Recommend corrective actions and verify them through laboratory or site trials.

6. Technical & Commercial Support

- Work closely with Sales/Business Development teams to convert technical leads into successful product approvals.

- Benchmark proposed admixtures against competitor products.

- Prepare trial reports, product recommendations, and technical data for customers.

- Support customer complaints and provide technically justified corrective solutions.
