the limit concentration of sulphate is 1000 ppm after that "sulphate resistant cement" should be used
Advantages of using sulphate resisting cement,It is used in marine constructionUsed in foundations and basements where soil is infested with sulphates.Concrete to be used in construction of sewage treatment works.Used in fabrication of pipes which are likely to be buried in sulphate bearing soil.
Lime does raise the pH level of your soil; however Sulphate is the one that lowers it.

Sulfate is a chemical compound containing the sulfate anion (SO4^2-). It is commonly found in minerals, soil, water, and many biological processes. Sulfates are often used in industry, agriculture, and medical applications.
Soil poison, also known as soil contamination, occurs when toxic substances are present in the soil at levels that could harm humans, animals, or plants. This can happen due to the release of chemicals from industries, agricultural activities, improper disposal of waste, or accidental spills. Soil poison can have detrimental effects on ecosystems and can limit the ability of the soil to support healthy plant growth.

Sulphate Resistant Portland Cement (SRPC) is a type of cement specifically designed to withstand high sulphate concentrations in soil and water, which can cause deterioration in standard cement. It is produced by modifying the chemical composition of ordinary Portland cement to reduce the amount of tricalcium aluminate (C3A), which is susceptible to sulphate attack. SRPC is commonly used in structures exposed to aggressive environments, such as sewage treatment plants, foundations in coastal areas, and concrete exposed to sulphate-rich soils. Its durability enhances the longevity and performance of concrete in challenging conditions.
Aluminum Sulphate helps create an acid soil condition for plants. Ammonium Sulphate is a fast release, quick acting source of nitrogen.

Asphalt is a petroleum based product. It is mixed with rock and it acts like a binder and when layed and compressed, it makes a smooth surface like a road. soil cement is rock mixed with portland cement with enough water added to bid it together. It's normally used as a base for a road. it's pure mineral with water.
Sandy soil is better than clay soil for under cement slabs because it is more stable and allows for better drainage. Sandy soil has good compaction properties, which makes it less likely to shift and settle over time, providing a more stable base for the cement slab. Clay soil, on the other hand, is prone to shrinking and expanding with changes in moisture levels, which can lead to cracks and damage in the cement slab.
LVC typically stands for "liquid limit, plastic limit, and shrinkage limit." These are three key parameters used in soil testing to assess the plasticity and behavior of soil. Liquid limit measures the moisture content at which the soil transitions from plastic to liquid state, plastic limit defines the moisture content at which the soil can be molded, and the shrinkage limit indicates the moisture content at which further drying will not cause the soil to shrink.
sandy soil drains water
stony soil is soil that has stone or rocks in it or it can be gravelly with a cement layer above 80 cm.

You can naturally add sulfur to soil by using elemental sulfur, gypsum, or composted organic matter like manure or plant residues. These sources release sulfur slowly into the soil, helping to improve soil fertility and plant growth.
If the parent material is resistant to weathering, it will break down at a slower rate compared to more easily weathered materials. This can lead to the formation of soils with higher mineral content. However, prolonged resistance to weathering can limit soil formation and fertility in the long term.
