Designing Architectural Concrete Mixes

1972/11/01 · Except for the possible introduction of color, as-cast finishes very likely will not require that the mix design be different from the kind used for structural concrete. With these finishes it might, however, be necessary to design the

Cost & programme

Concrete frames also provide the inherent benefits of fire resistance, excellent acoustic and vibration performance, thermal mass and robustness – all at no extra cost. Specialist concrete frame contractors have expertise that can reduce costs and maximise value when their input is harnessed early in the design process.


A. Design mixes may be prepared by a qualified independent testing agency or by qualified precast plant personnel at structural precast concrete fabricator’s option. B. Limit water-soluble chloride ions to the maximum percentage by weight of cement permitted by ACI 318 or PCI MNL 116 when tested in accordance with ASTM C 1218.

MICA – Concrete Quarterly features White Lion House

A light-coloured mix was chosen, with an acid-etched finish to tie in with the renovated brise-soleils on the adjoining Centre Point House. The architects opted to create the pattern in precast concrete, using flexible formwork liner, as a way of controlling the detailing. The method also brought time and sequencing benefits.

Precast concrete

Stormwater and rainwater can be used in the precast concrete mix design, thereby reducing mains water consumption and allowing highly alkaline wastewater to be recycled into the mix. Precast concrete methods favour the reuse of formwork, and off-site manufacturing allows most manufacturing waste to be recycled.
