Questions about the Concrete Properties poster

What’s on the Concrete Properties poster?

A definition and 6 facts worth remembering. Concrete is strong in compression, weak in tension, and keeps changing for months after it is placed. Tensile strength is near a tenth of compressive; Reinforcement carries the tension instead; Elastic modulus rises with strength, slowly; Shrinkage and creep continue for years; It is alkaline, and that protects the steel; Strength is quoted at 28 days by convention; Compressive strength — Often 25 to 50 MPa; Density, reinforced — About 25 kN/m³; A slab that cracks on the first day is shrinking, not overloaded.. Educational reference. Strength classes, testing and acceptance are governed by the concrete standard and specification.

Who is the Concrete Properties poster for?

Concrete Properties belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning civil materials can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Concrete Properties poster?

Before assuming a slab will behave the way the calculation says. A wall chart earns its place by being glanceable from where the work is happening, so Concrete Properties belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Concrete Properties?

Aggregates, Bituminous Materials and Cement Types sit alongside Concrete Properties in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AggregatesBituminous MaterialsCement Types

Is the Concrete Properties poster free to download and print?

Yes. Concrete Properties downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Concrete Properties poster print at?

Concrete Properties is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Concrete Properties loses nothing.Printing guide
