High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties

Peterson, Markus LU (2008) In Report TVBM 1027
Abstract
Cast in-situ concrete is the most frequently used materials technology worldwide within

production of structural frames in multi-storey residential buildings. In Sweden, this

technology dominates the market but is challenged by other competitive production methods.

The criticism concerns issues as for instance short slab spans (limited flexibility for future

refurbishment), long production times, unhealthy work environment and indoor air problems.

Many of these disadvantages are due to the fact that by tradition ordinary low-grade concrete

is used in house building. Extensive concrete materials research on high-performance

concrete (HPC) and self-compacting concrete (SCC) has... (More)
Cast in-situ concrete is the most frequently used materials technology worldwide within

production of structural frames in multi-storey residential buildings. In Sweden, this

technology dominates the market but is challenged by other competitive production methods.

The criticism concerns issues as for instance short slab spans (limited flexibility for future

refurbishment), long production times, unhealthy work environment and indoor air problems.

Many of these disadvantages are due to the fact that by tradition ordinary low-grade concrete

is used in house building. Extensive concrete materials research on high-performance

concrete (HPC) and self-compacting concrete (SCC) has revealed opportunities to counter the

criticism, but the technologies are not yet utilised in house building to large extent. The

research project aims at investigating the potential of HPC and SCC for competitive

production, structural design and function of structural frames of cast in-situ concrete in house

building.

The first part of the research project is dominated by production studies performed in field

with the aim of investigating the ‘real’ potential of SCC addressing technical/practical and

economical issues. These case studies consist of observations and measurements of the

consequences when normal concrete is replaced by SCC. The result shows that SCC has a

large potential for both increasing the production efficiency and improving the work

environment.

In the second part of the project, the theoretical potential of HPC is investigated by several

parameter studies where HPC is compared with ordinary concrete as well as an interview

study focusing on building process issues. The main conclusions from these studies are that

use of HPC can reduce the production time strongly (by rapid drying and strength

development), increase the slab span significantly (through utilisation of increased tensile

strength and E-modulus) and also increase the building function (increased flexibility,

acoustic and indoor air quality).

When it comes to technical and building process related obstacles for the implementation of

HPC and SCC, these are analysed and described together with proposed solutions. (Less)
