About This Product
The Los Angeles abrasion test measures how well coarse aggregate resists wear and impact, a property that matters for road and construction stone. The sample is loaded into the drum together with the steel balls, the cover is closed and the drum is turned for a set number of revolutions counted on the revolution counter. The balls tumble against the aggregate, and afterwards the material is collected on the tray and examined for wear. The machine is used in civil engineering laboratories. School Lab Equipment India supplies the Los Angeles Abrasion Testing Machine across India and can export it to Cyprus, Jamaica, United States, Serbia, Luxembourg and Bahrain.
