and lack of dust. The Ottawa sand was chosen by the American Society for Testing and Materials (ASTM) as the standard sand to be used in testing cement and the strength of concrete. Because the sand is typically regarded as a standard often detailed mineralogical analyses would not be required prior to experiments. (Ravia et al. 2008).

Making Cement And Concrete Crafts | Mixes & Sealers

This Portland mix is the cheapest of the concrete mixes. Demold time is 24 hours, but it will take another 2 days for the cement to reach its final color. This will dry to a light-medium grey. The directions call for at least a 3:1 ratio of sand to cement, but this is unnecessary for most cement & concrete crafts.

Types of Sand & Classification of Sand. Followings are the classification of Sand: Based on the grain size of the particle, sand is classified as Fine Sand(0.075 to 0.425mm), Medium Sand(0.425 to 2mm), and Coarse Sand(2.0 mm to 4.75mm) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand.

Alluvial deposits at the banks of the river mainly comprise medium plastic sandy silt (ML) and sandy lean clay (CL). At the river center, however, this deposit consists of pervious sandy gravel with a coefficient of permeability in the order of 3.290 × 10 −4 cm/s. Hence, it is proposed to remove both colluvial and alluvial deposits from the ...

European Journal of Scientific Research

Concretes made from alluvial sand (BSN) had the best compressive strength (33 MPa). Concretes made from quarry sand (BSG) and the mixture of two sands (BMS) had compressive strengths of 28 and 30 MPa respectively. The alluvial sand had proven to be of little benefit for making concrete compared to crush quarry sand used in construction projects.

Types of Piles: Their Characteristics and General Use

of concrete piles were devised. These early concrete piles were the cast-in-place type. Further development of the concrete pile led to the precast pile and, relatively recently, to the prestressed concrete pile. The need for extremely long piles with high bearing capacity led to the use of concrete-filled steel-pipe piles about 50 to 60 years ago.

The effect of natural sand composition on concrete strength

The strength of the concrete is related to the composition of sands used in concrete mix. Hence, the content and type of clay, and the percentage of feldspar and mica in the aggregates should always be determined before they are used in the concrete mix. The presence of clay in the natural sand reduces the concrete strength by nearly 10 MPa.
