QUALITY CONTROL

Introduction

Sermix aim of quality control policy is gaining more than customers satisfaction with the highest technology we are sure to submit our customers the optimum product in the least time span.Sermix start with two full automatic computerized batch plants and twenty three truck mixers 10 m3 load for each , five mobile pumps , four chiller units , sand screen , and highly qualified , professional , well trained staff.

Visual inspection for each sand and aggregates receiving loads , checking delivery ticket and sampling  according to sermix quality control plan.

Routine test according to sermix quality plan performed to check the quality of receiving materials.

Aggregates storage separately each size in suitable bins.

Cement storage separately each type in suitable water proof silos .

Additives storage separately each type in suitable weather tide tanks (specially delivered by additives company).

Water storage in underground isolated tanks and chilled water at well isolated steel tanks.

all designs done according to international and national specifications and codes.

strength testing will be from an essential part of assessment of compliance with the specifications.

special designs also prepared according to client projects specifications studies with suitable safety factor.

following up this design mixes on daily bases by sampling of each strength of fresh concrete produced for statistical studies report.
