If you are looking for the difference between sea sand and river sand? Then you came to the right place.
In terminology, sea sand is sand taken from coastal areas, then river sand is sand taken from rivers and often comes from cold lava as a result of volcanic eruptions.
Sea Sand VS River Sand
Here the 8 difference between sea sand and river sand:
As far as appearance tone, the sea sand is hazier, dull earthy colored, and lighter. The shade of river sand is generally brilliantly yellow.
From the part of molecule size, the grain size of river sand is coarser, with moderate surface harshness and fewer debasements. Sea sand is fine, even some like powder, this is by no means utilized.
As far as molecule parts, sea sand, by and large, has pieces like shells, while river sand has stones of various sizes.
Sea sand has a very fine grain texture, so that when it is mixed with cement mortar, the binding power of the sand is not strong enough, so it is easy to break or come loose. In general, for structures, it is better to use river sand with coarser and sharper grains.
Finer sea sand requires more cement to bond, so it risks weighing on the budget. Sea sand has salty properties, so there is a risk of corroding the steel reinforcing structure and reducing the strength of the structure. In addition, the salty nature can make cement lose its adhesion
The river sand utilized in the development has certain details. During the time spent river sand screening, river sand is by and large partitioned into 4-8 lattice, 8-16 cross-section, 10-20 cross-section, 20-40 cross-section, 40-70 lattice, and 50-100 lattice, which alludes to the number of sand particles inside a one-inch circle. There is no such fine and clear principle grouping for sea sand.
Snatch a handful of sand and then beat it off. It’s sea sand that feels tacky and doesn’t spotless. In the event that it’s not tacky, it’s river sand.
Taste the taste, tracked down that pungent is sea sand, not pungent is river sand. As of now, there are additionally numerous Sea Sands that have been desalted. We can absorb the sands of the water for a while and taste the flavor of the water. The pungent and astringent one is Sea Sands.
However, it cannot be denied that not all areas have river sand because they only have sea sand. If there is no other solution, it is better if beach sand is mixed with local sand other than the river sand, this is none other than to reduce the salt content of the sand.
Meanwhile, for making a block or paving blocks, the use of river sand in the mixture can support the binding power and strength of the product.
The principal piece of sea sand is silica, the gem stage is essentially quartz, feldspar and trash particles are less, mica content is less, and the roundness is additionally acceptable.
The silicon substance of river sand is lower, the metal particles, for example, calcium and aluminum are more, and the mica sheet content is likewise more. However, this is just a normal circumstance, as a rule, at times there are exceptional cases, and it is hard to have explicit quantitative pointers.
Sea sand is similar in properties to river sand. It is also highly accepted in the construction industry due to its high purity and particle size uniformity.
What will you choose?
What is better, river sand or sea? This question is quite complex. The extent of this or this type of sand is directly dependent on the customer’s need and the seriousness of the facility during the construction phase. These parameters are important for the price, the size modulus, the impurity percentage, and also the filtering coefficient. According to these parameters for a particular work, the selected sand is completely suitable, it can be applied safely. The place of production does not matter, because the quality and the more expensive river sand are not very suitable for some tasks, so the sea sounds great.
Sand is an important component of a concrete mix, so its preference should not be mentioned. For each kg of cement, about 3 kg of sand will be required for the construction of the foundation. As with any component, specific requirements are presented. About sand must be guided by independent kneading concrete, GOST 8736-93 “sand for construction work. Technical Conditions ” (hereinafter just).
There are many varieties, each different:
- chemical composition;
- physical properties;
- mining method.
In addition to the differences in the listed properties distinguish sand depending on the fraction of the gamble in GOST. In parentheses is the class that the material of this fraction can contain depending on the quality indicators.
Tips for Finding High-Quality Sand
Sand is the basic material of all construction activities, so many do not pay attention that the quality of sand greatly affects the quality of the building foundation that we are building. So that you don’t choose the wrong quality sand, let’s take a look at the explanation of how to see sand with good quality below.
1. Sand Grains Are Not Hard and Sharp
Avoid choosing sand that has hard and sharp grains, this can reduce the quality of the sand you choose. The mixture of construction materials can mix unevenly due to the hard and sharp grains of sand.
2. Sand Should not have a mud content of around 5%
If the sand has a silt content of more than 5%, it must be washed so that the silt content in the sand disappears from the sand. Sludge in the sand can enter into cement processing etc. and can make the quality of the processed mixture less strong during installation.
3. Must Have strong Durable Properties
The sand must have either immutable resistance or very strong resistance. The sand must be tested using a variety of methods to see if it is tested for strength.
