MASTERTHESISHedaredSand&BetongAB- Better quality and work environment -

BackgroundWe manufacture concrete blocks for retaining walls in gardens, on industrial sites and along

highways. The blocks are assembled in layers which are connected with vertical glass fiber

pins. The block dimensions (both internal and external) are critical for a perfect fit. Today we

check the dimensions manually.

Tasks• Develop and automate the geometry check to ensure that our blocks meet the

expectations of our customers (instead of solely relying on the human eye).

• Find a way to analyze which anomalies early in the process that causes deviations later

on in the process.

• Review and develop the possibilities of mounting laser scanner, camera etc. to

enhance the surface control of our blocks.

Goals

Expected results of the master thesis:

• Practical use of modern technology (laser scanning or imaging) to find geometric

deviations.

• Developing and formulating solutions to reduce the rejection of blocks that do not

meet market expectations.

• Identify further focus areas and work

MeansOffice, computer and software will be arranged by university and Hedared Sand & Betong

AB.

ConductionThis thesis needs two students. The time period: December 2020 to March 2021.
