A fresh set every day. Short, practical, and written the way it actually matters on site.
Standard Penetration Test
Counting hammer blows to drive a sampler 300 mm into the borehole.
On siteThe N-value is the fastest field indicator of density and correlates to bearing capacity.
Live Load
Movable, variable loads from occupancy, furniture and people.
On siteIS 875 Part 2 fixes the values by use — residential, office and storage differ sharply.
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.
Cube Test
Crushing cured cubes to confirm compressive strength.
On siteStandard at 7 and 28 days in India. The 7-day result is roughly two-thirds of the 28-day value.
Scaffolding
A temporary framework giving access and working platforms.
On siteIt carries people, not the structure. Overloading it with stacked material is a routine and serious hazard.
