of ingredients of a concrete mix is in the terms of parts or ratios of cement, fine and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate. The proportions are

Concrete mixer is intended for personal use for mixing of concrete and mortar. IT IS NOT DESIGNED FOR PROFFESIONAL USE. Assembly Two people assist in assembly recommended. A. Wheels: Use 2 lock pins and two flat washers for each wheel. For safety, fold each side of the pins in the outside.
Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

roportioning the mix components for a con-crete masonry unit (CMU) is an important step in producing high-quality units. A well-proportioned mix can improve a unit’s physical properties (compressive strength, unit weight, absorption) so they meet or exceed ASTM C 90 Standard Specification for Load-Bearing Concrete Masonry Units.

BRICKS AND BLOCKS. Metric bricks are a little smaller than the old imperial one. New bricks can be bonded into old brickwork by slightly increasing the mortar bed joint. There are a variety of sizes available and they differ from country to country.
DIN Standards are the results of work at national, European and/or international level. Anyone can submit a proposal for a new standard. Once accepted, the standards project is carried out according to set rules of procedure by the relevant DIN Standards Committee, the relevant Technical Committee of the European standards organization CEN (CENELEC for electrotechnical standards) or the ...
ACI METHOD OF PROPORTIONING CONCRETE MIXES The ACI Standard 211.1 is a “Recommended Practice for Selecting Proportions for Concrete”. The procedure is as follows: Step 1. Choice of slump Step 2. Choice of maximum size of aggregate Step 3. Estimation of mixing water and air content Step 4. Selection of water/cement ratio Step 5.

Different types of standards. What are the different types of standard? Standards all have the same basic purpose of setting out agreed principles or criteria so that their users can make reliable assumptions about a particular product, service or practice.
specifically developed for concrete pavements, the DOE method is applicable to concrete for most purposes, including roads. Since DOE method presently is the standard British method of concrete mix design, the procedure involved in this method is described instead of out dated Road Note No 4 method.

ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres: 1) Directive 99/92/EC (also known as 'ATEX 137' or the 'ATEX Workplace Directive') on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.
ASTM's water testing standards are instrumental in specifying and evaluating the methods and facilities used in examining the various characteristics of and contaminants in water for health, security, and environmental purposes.

other injury. The safety of all personnel must be paramount when handling, mixing, and applying chemical disinfectants. Appropriate PPE (e.g., gloves, goggles, masks) should be worn. It is essential that C&D personnel are trained on the proper mixing and application procedures as well as the hazards of the products they will be using.
Concrete mix design is mostly a theoretical calculation which gives us the ratio of cement, aggregates and water to make the concrete mix of desired strength and workability.
