ASTM A325
Prior to its withdrawl in 2016 the ASTM A325 specification covered high strength heavy hex structural bolts from 1/2″ diameter through 11/2″ diameter These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts

Ultrasonic Pulse Velocity—Compressive Strength
Characterization of 28day compressive strength of Portland cement mortars is normally performed by destructive testing [1 2] but nondestructive methods as UPV were not extensively used In this paper correlation between 28day compressive strength and average ultrasonic pulse velocity is performed taken into account that correlation is a

Cement Types
Construction documents often specify a cement type based on the required performance of the concrete or the placement conditions Certain cement manufacturing plants only produce certain types of portland cement What are the differences in these cement types and how are they tested produced and identified in practice?
