A fresh set every day. Short, practical, and written the way it actually matters on site.
Slump Test
Measuring how far a moulded cone of fresh concrete subsides.
On siteThe quickest workability check on site, and the fastest way to catch an over-watered load.
Contour Line
A line joining points of equal elevation on a plan.
On siteClosely spaced lines mean steep ground. Reading the spacing tells you the earthwork before any calculation.
Characteristic Strength
The strength below which no more than 5% of test results are expected to fall.
On siteM25 means 25 N/mm² characteristic — not average. The target mean design strength is deliberately higher.
Silica Fume
An ultrafine pozzolan that fills voids between cement grains.
On siteGives very high strength and low permeability. Essential to most high-performance mixes.
Cohesion
Shear strength that exists in a soil even with no confining pressure.
On siteClay has it, clean sand has almost none — which is why sand needs shoring and stiff clay may stand briefly.
