How Is Lime Specified Into Mortars? Portland cement-lime mortars are specified in two steps. First, the mortar type must be determined based on the strength required for the application. Secondly, a choice must be made between specifying proportions or properties listed in ASTM C270.

The determination of the proportions of cement, aggregates and water to obtain the required strengths shall be made as follows: a) By designing the concrete mix, such concrete shall be called design mix concrete, or. b) By adopting nominal mix, such concrete shall be called nominal mix concrete.

Grades of Concrete with Proportion (Mix Ratio) We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting.

The ratio to mix mortar is historically accepted as 1:3 of sand and cement. Mortar is a mixture of cement used in the building trade to hold bricks together. The type of sand and cement mixture needed will dictate the exact ratio. This varies according to the needs of the task: above ground is 5:1, below ground is 3:1 and internal walls is 8:1.

Mortar Mixes Here are seven common and uncommon mortar mixes. They are types N, M, S and O. There is also mortar for glass block, straight lime mortar and type K. Type K is used solely in historic preservation. Each one has a certain proportion of Portland cement, hydrated lime and sand. Mortar proportions are always expressed in that order.

The concrete mix design involves various steps, calculations and laboratory testing to find right mix proportions. This process is usually adopted for structures which requires higher grades of concrete such as M25 and above and large construction projects where quantity of concrete consumption is huge..

The common method of expressing the proportions 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
