Learn 5 civil engineering concepts today
A fresh set every day. Short, practical, and written the way it actually matters on site.
Soling
A packed layer of stone or brick placed below a foundation or floor.
On siteIt gives a firm working base and breaks capillary rise from the soil below.
Grouting
Injecting a fluid cement mix to fill voids or gaps.
On siteUsed under base plates and in post-tensioned ducts, where a void means an unprotected tendon.
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.
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.
Bending Moment
Internal moment causing a member to curve.
On siteMaximum at midspan for a simply supported beam, and at supports for a continuous one.
