A fresh set every day. Short, practical, and written the way it actually matters on site.
Admixture
A chemical added to concrete to change a specific property.
On sitePlasticisers buy workability without adding water — the correct answer when a mix looks stiff.
Aggregate Grading
The particle size distribution in a mix.
On siteWell-graded aggregate needs less paste for the same workability, so it is cheaper and stronger.
Under-Reinforced Section
A section with enough steel that it yields well before the concrete crushes.
On siteFails slowly with visible cracking and deflection. This ductile warning is the whole point.
Permeability
How readily water flows through a soil mass.
On siteDecides whether an excavation needs dewatering and how fast a clay layer will consolidate.
Reduced Level
The height of a point above the chosen datum.
On siteEvery foundation depth, plinth and floor level on a drawing is expressed as an RL.
