Materials used in the cement stabilization layer must meet the requirements of specifications or regulations. The gravel used in the stabilizing layer must be clean, hard, angular and continuously leveled. The grain size of the aggregates must comply with the provisions of gradation No. 1 of Table 6.2.4 of the “Technical Specifications for the Construction of the Base Course of the Road Pavement” (JTJ034-2000). Needle, flakes (≥1:3) particle content less than 20%.
As long as it meets the above indicators, it can be used if all three parties agree.
How to calculate the technical quantities of cement and gravel for a soil stabilized in cement 20 cm thick recycled 8% cement + 30% gravel?
1; Each cubic meter of 4% cement stabilized gravel is equivalent to 2,032 kg (maximum dry density).
2; The amount of dry mix per side: 2032/1.059 = 1918.791 kg.
3; Water consumption: 2032-1918.791 = 113.2087 kg.
4; Consumption of aggregates (gravel + stone chips): 1918.791/1.04=1844.992 kg.
5; 1# gravel=1844.992*34%, 2# gravel=1844.992*40%, 3# stone chips=1844.992*26%;
6; -1844.992=73.799kg.
Summary: cement 73.799: aggregates 1844.992: water 113.2087;
1# gravel: 2# gravel: 3# stone chips = 34%: 40%: 26% Mixture (i.e.: 1# gravel = 1844.992*34%, 2# gravel = 1844, 992*40%, 3# stone chips = 1844.992*26%
5% can be calculated according to the above
Thank you for your work, I hope. you will adopt it!
To calculate the technical quantities of cement and gravel, you must first determine the volume of soil stabilized with cement Assuming that the length of the road to be paved is L and. the width is W, the volume V of cement stabilized soil is:
V = L × W × 0.2
Where 0.2 refers to cement stabilized soil . The thickness ist of 20 cm.
Next, calculate the quantities of cement and gravel. According to the meaning of the question, the mixing ratio used is 8% cement + 30% gravel, therefore:
- The quantity of cement: 0.08 × V
- The amount of gravel: 0.3 × V
Replace the above formula with:
-Amount of cement: 0.08 × L × W × 0.2
-Amount of gravel: 0.3 × L × W × 0.2
It should be noted that the dosage here is only a theoretical value. In real situations, dosage may vary slightly due to wastage or other factors. Therefore, adjustments must be made based on actual conditions during the construction process.
