Adam Neville is a renowned international authority on concrete and author or co-author of nine other books, the latest of which are Neville on Concrete and Concrete: Neville’s Insights and Issues, as well as over 250 research and technical papers.

He has very extensive international experience as a consultant and investigator of problems and failures in a variety of structures.

In certain instances the addition of superplasticizers and viscosity modifier are added to the mix, reducing bleeding and segregation.

Concrete that segregates loses strength and results in honeycombed areas next to the formwork.

These two mixes were mix M1 (SCC, 0% fibers) and mix M3 (CFRSCC, 0.50% fibers).

Eleven RC beams were tested to investigate three different repair configurations: flexural-top patch, flexural bottom patch and shear span patch.

This type of concrete must meet special project requirements in terms of placement and flow.

Self-compacting concrete with a similar water cement or cement binder ratio will usually have a slightly higher strength compared with traditional vibrated concrete, due to the lack of vibration giving an improved interface between the aggregate and hardened paste.

The segregation resistance of the concrete mixtures was evaluated by using the sieve stability test.

The purpose of this study is to examine the effects of discrete Pitch-based carbon fibers on the fresh properties of self-consolidating concrete (SCC).

Ten different carbon fiber-reinforced self-consolidating concrete (CFRSCC) mixtures were produced with two water/binder (W/B) ratios of 0.35 and 0.4, and 0%, 0.25%, 0.5%, 0.75%, 1% carbon fibers by concrete volume.

Self-compacting concrete is a non-segregating concrete that is placed by means of its own weight.

The importance of self-compacting concrete is that maintains all concrete’s durability and characteristics, meeting expected performance requirements.
