Architectural masonry is the evolvement of standard gray concrete masonry blocks into aesthetically pleasing concrete masonry units (CMUs). These architectural blocks include a wide array of bricks which vary in shape, size, and texture, and can be used as a standalone or in conjunction with other standard masonry materials.
In general, a minimum fall of 1 in 80 will help to prevent ponding of water. Roof Systems Lightweight Concrete and Screeds allows architects and building contractors greater versatility in design and performance of a flat concrete roof or deck. It provides a very effective and efficient method of insulating the concrete base from intense heat ...
FUNDAMENTALS OF HIGH PERFORMANCE CONCRETE. 2ND EDITION. This book is a coordinated treatment of the subject of normal and highstrength high performance concrete, reflecting the latest provision of the American Concrete Institute (ACI) codes. There are 13 chapters: (1) general performance characteristics; (2) permeability effects on performance ...
The patented mixer design allows the consistent and highquality ed concrete production of any density in the range of 300 – 1000 kg/m3. As the concrete hardens, the bubbles disintegrate leaving air voids (cells) of similar sizes. ed cellular concrete is generally aircured.
3. Proven low initial cost. Architectural precast concrete is used widely by office building developers nationwide. They tell us it is their cladding material of choice because it offers a high quality "look" at a very economical price. 4. Long term maintenance is almost negligible. All you need to do is recaulk the precast joints after 15 to ...
A high strength concrete particularly useful for precast, prestressed products comprising by weight of the wet concrete mix, 8 to 60 percent cement, to 20 percent smoothsurfaced, vesicular, expanded perlite, 5 to 30 percent water, 0 to 12 percent pozzolan, and fine aggregate and coarse aggregate as appropriate and available in the circumstances.
overview Structural lightweight concrete made with rotary kiln produced structural lightweight aggregate solves weight and durability problems in buildings and exposed structures. Structural lightweight concrete has strengths comparable to normal weight concrete, yet is typically 25% to 35% lighter. Structural lightweight concrete offers design flexibility and substantial cost .
