Updated to clarify that
Limestone combinations relate to the Cement Strength - 32.5 N/mm2 & 42.5
N/mm2. |
|
|
|
|
|
|
|
Mix Design zone updated
to cover combinations with pre-mixed PLC clinker mixes. |
|
|
|
|
|
|
|
|
|
PLC clinker mixes come
with a maximum Limestone content of 15%. |
|
|
|
|
|
|
|
|
|
|
|
Therefore when PLC is
mixed with secondary constituents the Limestone % of the TOTAL mix will be
< PLC mix %. |
|
|
|
|
|
|
PLCS clinker i.e. PLC+SR
clinker option is added. The Limestone % calculations are as PLC. |
|
|
|

Combined mixes with +SR
are now displayed correctly. |

User can control the h /
L factr used in Edge Restraint to C766 by entering Edg h/L i.e. Edg 0.1 Edg 0.15
Edg 0.2 etc. |
|
|
|
|
|
|
The C766 default h / L
is 0.1 but 0.2 may be used where the wall is cast against an existing wall. |
|
|
|
|
|
|
|
|
Otherwise, for C660 or if
no R / Rj factor is required to C766, enter Edge as before. |

User can now specify the
CIRIA T1 derived Ground Slab values for a C660 design in Cell I144 |
|
|

|
For a traditional design,
using 1.3 x wall H and steel formwork, specify 1.3H |
|
|
|
|
|
|
|
|
|
|
For a design using the
CIRIA T1 Ground Slab program enter Slab. |
|
|
|

|
|

|
|
|
|
HAC no longer gives the
user the option of using the T1 charts published in C660. |
|
|
|
|
|
|
|
|
|
The C660 T1 values are
derived from the C660 CIRIA T1 program. |
|
|
|
|
|
|
|
|
|
|
|
For a C766 ground slab
design, HAC-PRO only uses the C766 CIRIA T1 Ground Slab program values. |
|
|
|
|
|
|
|
Note. The C766 T1 values
are revised from the C660 T1 values, especially in respect of GGBS. |
