Compressive strength of gravel itself | DIY Home Improvement
In any case, the compressive strength of an individual gravel particle, if it is stone, is very high, often 20,000 pounds per square foot or higher. You are probably not talking about the compressive strength of a single particle, rather you are probably interested in the compressive strength of a layer of gravel.

The compressive strength was observed to be higher than the control (0% limestone mortar) when 5 wt.% natural limestone was added to the mix, however all other mixes were lower than the control. For instance, adding 5 wt.% of natural limestone (CN-5%) increased the compression strength by 8% at 28 days to 54.0 MPa, while the lowest was 40.6 MPa

Crushed limestone has several important advantages over river gravel as an aggregate for concrete. First, for a given amount of cement in the mix, crushed limestone concrete will have an approximately 10% strength advantage. This strength advantage comes from the fact that cement bonds tighter to limestone than to a slick/smooth gravel and the

Sahu et al. (2003) observed that concrete made using crushed rock sand attained the comparable compressive strength, tensile strength and modulus of rupture as the control concrete. Sahul Hameed and Sekar (2009) concluded that the compressive strength, split tensile strength and the durability properties of concrete made of quarry rock dust are nearly 14% more than the conventional concrete.

The compressive strength of steel slag aggregate concrete, with 50 and 55% aggregates was marginally, about 2 MPa, less than that of crushed limestone aggregate concrete. Therefore, a coarse aggregate to total aggregate proportion of 50% may be adopted to minimize the weight effect of heavy steel slag aggregates.
