Experimental datasets on properties of river sand as an aggregate in replacement of crushed rock for interlocking stones production

The data explored the assessment of the quality of river sand as an aggregate in replacement of crushed stones which are widely used by majority of manufacturers in production of interlocking stones. Experimental tests carried out on river sand and crushed rock as aggregates include: Grain size distribution, Specific gravity, moisture content determination and Bulk density to determine the quality behavior parameters and (compressive strength) to determine the strength parameters. The data of the experiments are presented in Tables and Bar charts.

The data of the experiments are presented in Tables and Bar charts The data can be adopted for governmental policy on low-cost housing scheme production for the benefit of low-income earners.
The data provided conducive room for further studies on the reliability of local building materials in the building industries.
The data provided detailed experimental procedures on how river sand could be used instead of crushed stone thereby reducing its production cost.

Data
The data assessed the usefulness of available river sand in replacement of crushed stones in the production of interlocking stone. Related articles are [1][2][3][4]. The data presented in Tables 1-9 were obtained from the analyses of property parameters of river sand and crushed rock to determine its suitability for construction activities. The behaviour of 100% RS, 50%/50% RS/CR, 100% CR as indicated in Tables 1-9 illustrated that all the specimens met required standards but River sand had the highest value [5][6][7][8][9][10] The variance in the value of aggregates in moisture content determination, specific gravity and bulk density determination were equally illustrated in the tables. Data of grading sizes parameters are shown in Figs. 1-3 and they were all in conformity with the standard requirements [8][9][10].

Experimental design, materials and methods
The specimens of fine aggregate used for this data were obtained from Ota and Atan Tipper garage, Ado-odo Local Government Area, Ogun State, Nigeria. The River sand (RS) and crushed Rock (CR) used were; (100%RS), (100%CR) and (50%RS: 50%CR). Ordinary Portland cement (OPC) grade 42.5N was used and it was supplied in good condition. Portable water used for the study conformed to required standard [11]. The experimental procedures were carried out in the following order: 72 interlocking concrete cubes were produced under controlled temperature with ratio 1:3 and 1:4 respectively and   it was cured through immersion method. Compressive strength of concrete cubes was determined after curing for 7 days, 14 days, 21 days and 28 days respectively. To provide a good justification for the test results, several tests such as grain size distribution, specific gravity, moisture content determination and bulk density were conducted on the samples to determine its physical properties and suitability. However, various experimental procedures conducted on engineering properties of river sand and crushed rock were in conformity with the recommended standards [5].
The results of compressive strength for the three samples are shown in Figs. 4 and 5 and methods for mixing, curing, and strength test parameter were strictly followed and they were all in accordance to the standards [12][13][14][15][16][17][18][19]. Figs. 4 and 5 showed differences in strength parameters of the samples used. Thereby, the River sand had the highest compressive strength value with ratio (1:3) over Crushed rock which is most widely used by the interlocking stones manufacturers with assumption of colour resemblance to ordinary Portland cement. The data presented on river sand is a proof to be cost effective when compared with previous studies on crushed rock [1][2][3][4]. The outcome of the strength test revealed the performance and standard of local building materials in low cost housing production [19,20]. The presentation of data is also similar to that of [21], the experimental procedure of data presented took into consideration the recommendations of [22][23][24].
