Approximate weight

18 short tons

High confidence

About 1.8 short tons per cubic yard for sand-cement mortar; close to concrete but without coarse aggregate. A planning figure, not a specification. Confirm the density with your supplier before ordering by weight.

Conversion factor applied
1.8 short tons per cu yd

Mortar volume is worked out from the joint dimensions across a wall, and converting it to weight matters mainly for ordering the sand and cement that make it. The density sits below concrete because there is no coarse aggregate, only sand and binder. The figure most often underestimated is not the density but the volume itself: joints look thin, but across a full elevation the mortar in a single-wythe wall amounts to a substantial proportion of the wall's volume, and perpends consume as much as beds.

Add the equipment this sizes

This result is a specification — 18 short tons — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

How much mortar does a wall actually need?
More than joints appear to suggest. Both bed and perpend joints across a whole elevation add up to a meaningful share of the wall volume, and the proportion rises as unit size falls — small units mean more joints.
Does mix ratio change the density?
Only slightly. Richer and leaner sand-cement mixes differ modestly in density; the ratio matters far more for strength, workability and durability than for weight.
Can I mix mortar in advance?
Only within its working life. Once it begins to stiffen, adding water to bring it back weakens the mix substantially. Batch to the rate of laying rather than mixing ahead.
