In recent years, there is a growing interest in the use of crushed sand obtained from limestone quarries in some countries where river sand is not widely available. Besides, the demand for aggregates to produce concrete is still high while natural resources decrease. The fines content in limestone is usually high (particles with a size of 0.15-0.7 mm) which can affect concrete properties in an ...

Aug 23, 2019 The tensile strength of the concrete also increases, if the replacement of fine aggregate is up to a certain percentage. Hence, one can replace the river sand up to 25%-50% in the concrete mixes. This type of replacement has a lot of advantages to the environment as well as human kind. Therefore, replacement of river sand with construction and ...

Jan 05, 2011 Lime, sand, and cement mix must be combined in the proper amounts to get a good lime concrete solution. Three generally mixtures exist to make this material, but two have been discontinued as they had been found lacking in long term integrity. The only viable option is a mixture that calls for a 1:1:6 ratio—one part cement, one part lime, and ...
