Mar 15, 2007· Walls built with a combination of concrete block, mortar and rebar are also popular for small yard projects. The mortar and steel rods lock the blocks together for additional strength. This article will focus on building retaining walls from newer segmental block systems, as well as building from traditional concrete.
Autoclaved aerated concrete (AAC, Aircrete) Autoclaved aerated concrete is a versatile lightweight construction material and usually used as blocks. Compared with normal (ie: "dense" concrete) aircrete has a low density and excellent insulation properties. The low density is achieved by the formation of air voids to produce a cellular ...
Guidelines for Durable Driveways, Carports Patios, Walks, Garage Floors • The Right Concrete Mix • Placing and Finishing • Joints Correctly Spaced • Curing for Durability "Concrete durability is the ability to resist weathering action, chemical attack, abrasion or any other process of deterioration.
Concrete blocks. Though history records the use of concrete blocks by the Romans, Greeks and even Egyptians (some of the twotonne blocks that make up the Pyramids are believed to be a primitive form of concrete), moderntype blocks were first cast, albeit in modest quantities, in around the middle of the nineteenth century.
Standard concrete units are primarily used for exterior loadbearing and foundation walls. Lightweight Concrete Block units are used for interior use, particularly because of its higher fire rating and sound absorbing properties. These concrete blocks come in four sizes and six styles, including Ashlar, Frog, Return Corner and Single Bullnose.

Generally speaking hollow blocks require a strength of /mm². For heavy reinforced retaining walls a typical design strength of 7N/mm² maybe required. Skene Group blocks produce all hollows to a 10N/mm² design strength, thus allowing Skene Group hollows to cover almost all likely specifications.
If the wall is grouted, then the grout simply has to comply with ASTM C476, Specification for Grout for Masonry, or be the same strength as the specified strength of masonry, but not less than a minimum of 2,000 pounds per square inch (psi).
Additional portland cement or SCMs may be used to obtain high early strength in concrete, except that the total amount of portland cement shall not exceed 700 lbs. per yd3 (415 kg per m3) unless otherwise approved by the Engineer. Color concrete shall conform to 3037.
Mesastone® textured masonry units are prefinished architectural concrete blocks manufactured with colored aggregates and pigment uniformly finished to an even texture. The MESASTONE textured surface resembles split face block but is more uniform, easier to .
Concrete Masonry Units manufactured by General Shale comply with all building code requirements and specifications. Please refer to the Concrete Masonry Products Insert Folder under the Library tab for more details. ... A range of high strength concrete building blocks, robust, load bearing units for use in either internal or external walls in ...
This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a unit weight in excess of 50 lb/ft 3[800 kg/m ]. The values stated in either inchpound or SI units are to be regarded separately as standard. The SI units are shown in
SANS Specifications for Concrete paving bricks. 1. The manufacturer has an equipped laboratory and tests batches of manufactured blocks. 2. Blocks comply with strength specifications which are tested by means of tensile splitting. 3. Blocks comply with abrasive resistance specifications. This means that blocks are only allowed a specified amount of "damage" due to friction.
Highperformance concrete (HPC) is a relatively new term for concrete that conforms to a set of standards above those of the most common applications, but not limited to strength. While all highstrength concrete is also highperformance, not all highperformance concrete is highstrength.
Key features and benefits. Extensive range of solid and hollow blocks. Standard sizes metric 450mm and modular 400mm ranges. Wide choice of accessory products. Produced nationwide. Available in High compressive strength. Class A1 Fire resistance. Excellent sound insulation. Low thermal conductivity and high thermal capacity.
Compressive Strength of Cylindrical Concrete Specimens. A test result is the average of at least two standardcured strength specimens made from the same concrete sample and tested at the same age. In most cases strength requirements for concrete are at an age of 28 days. Design engineers us the specified strength ƒ´ c to design structural elements.
Mar 09, 2014· The standard concrete block dimensions in some Asian countries such as the Philippines is 16 x 8 x 4 to 6 inches while a standard concrete masonry unit in the United States come in dimensions of 8 x 8 16 inches.
Explanation of different types of concrete are as below: Normal Concrete. The concrete in which common ingredients aggregate, water, cement are used is known as normal concrete. It is also called normal weight concrete or normal strength concrete. ... Strength of light weight concrete blocks varies from 7 MPa (1000 psi) 40 MPa (5800 psi).
Lightweight concrete can be specified using the notation LC for the strength class, LC30/33, which denotes a lightweight concrete with a cylinder strength of 30MPa and a cube strength of 33MPa. The lighter the concrete, the greater are the differences to be accounted for in the properties of the concrete.
Concrete Masonry Units also known as CMU are blocks used in the construction industry to form a concrete block structure like a wall or a fence. These are generally made up of concrete and aggregates of certain design mixtures depending on strength required but systems used as masonry units are nonload bearing in nature or do not and should not be allowed to carry any vertical loads at all.

tensile and flexural tensile strength according to ASTM standards (ASTM C39, 2001), TSE (TS EN 123905, 2002) and BS (BS EN 1338, 2003). At least five core samples (with a length to diameter ratio of 2:1) from each mixture of concrete paving block were subjected to the strength tests which were carried out in an instrumented and
