# Effective Microorganisms Composite Scupper Drain (EM-CSD)

### Problem Statement

Flash flood at road side drain causing traffic problem.

### Concrete Mix Design

The mix design prepared with 0.55 w/c ratio.

The quantity for EM was 10% by replacing the amount of total water content.

Concrete mix for control concrete mix (without EM) and EM concrete mix (with addition of EM) was the same.

The quantity for EM was 10% by replacing the amount of total water content.

Concrete mix for control concrete mix (without EM) and EM concrete mix (with addition of EM) was the same.
