Hardness depends on the ratio of portland cement to the aggregate (and the right amount of water). It used to be common to order different strengths with a term like "8 sack" meaning 800 pounds of portland per yard, and more sacks for more strength. 8 sack cures to about 3,000psi compression strength, more portland will give you higher compression strength. In my years of contracting I bought a whole lot of concrete.
At any rate, putting papercrete in standard concrete will reduce the strength compared to the same mix without the added papercrete. Conversely, adding more portland cement to papercrete will increase the strength.
Most probably NOT ! compressive strength depends on the hardness of the aggregate ! Cement by itself is not the greatest by itself but add stone to it and it increases. Even crushed glass will increase it !

IF WE ADD PAPERCRETE TO STANDARD CONCRETE ( 5%) THE COMPRESSIVE STRENGTH WILL INCREASE?
